The subject consists of two parts: the first one discusses some advanced topics in the field of engineering thermodynamics, the second one discusses the use of numerical methods for solving engineering problems. In particular, the modeling and numerical methods are applied to meaningful test cases relevant for engineering thermodynamics. The module of Advanced Engineering Thermodynamics is designed to complete the student's preparation in the field of engineering thermodynamics, whose basics were provided in previous subjects. This teaching module completes the theoretical background required by the design of devices with regards to the specific problems involving heat transfer. In particular, the subject discusses the thermal performance of energy components and mechanical systems and it provides some basic concepts about numerical fluid dynamics, including modeling of heat transfer systems. Finally, the basic concepts of environmental acoustics and lighting are provided in order to characterize the interaction of the devices with the end users. The module of Numerical Modelling is intended to provide the tools for the systematic and critical study of the main numerical models involving partial derivatives and used in various fields of engineering, which can be solved by appropriate numerical discretization methods. In particular, the module aims to provide the essential features for evaluating a numerical method in terms of the quality and the reliability of the numerical solution. Some test cases will be discussed in the field of advanced engineering thermodynamics.

The objective is to convey to the student in-depth knowledge of thermomechanical continuous media, thermodynamics and fluid dynamics, with particular emphasis on the concept of exergy, and, as regards the interaction with the end user, the basic elements of environmental acoustics and lighting. Additionally, the student should acquire the basic knowledge about the discretization methods for initial and boundary value problems involving elliptic, parabolic and hyperbolic partial differential equations (PDEs). Some emphasis is put on the basic mathematical properties (such as consistency, stability and convergence) of numerical methods. Students should become able to transform numerical models into systems of algebraic equations, and to solve these systems. The student is expected to learn how to use theoretical tools for studying heat transfer and energy balance of real systems, performing energy and exergy analysis of complex real systems (including using appropriate mathematical models) and managing complex energy conversion systems. Another objective is to convey to the student the ability to understand the regulations about environmental acoustics and lighting and to perform basic design calculations. Finally, the student is expected to learn the ability to implement in the MATLAB(r) software, or similar ones, some numerical models that describe engineering problems (particularly those relevant to engineering thermodynamics) and to relate their performances to the theoretical context. The student should also develop the ability of applying the numerical tools to the simulation of the behaviour of simple yet significant problems in applied thermodynamics.

Advanced engineering thermodynamics/Numerical modelling (Numerical modelling)

**Exam:** Computer lab-based test; Written test; Compulsory oral exam; Group project;

The exam consists of both a written part, related to the module of Numerical Modelling, and an oral part, related to the module of Advanced Engineering Thermodynamics. The final evaluation of the exam consists of the arithmetic mean (rounded up) of the two partial scores obtained in the two modules. With regards to the module on Numerical Modeling, the evaluation procedure is based on the following tests: a) solving some exercises on the main topics covered in the module (available time: 60n minutes), b) answering a series of multiple-choice questions with the help of MATLAB (available time: 45 minutes). No educational material is allowed in these tests. The mark of the written part will also take into account c) the optional preparation of a computational project during the semester, carried out by small groups of students on a numerical topic related to the group project developed in the advanced engineering thermodynamics module, and evaluated on the basis of the individual contribution. Tests a) and b) have a relative weight of 2/3 and 1/3, and overall they allow the sudent to obtain up to 28 points, whereas the computational project allows the student to obtain a higher mark than 28, including the laude. The mark of the written part will be communicated to students through the Portale della Didattica, together with the indication of when and where they can meet the teacher and check the results of their tests. Consistently with the expected learning outcomes, the written part of the exam aims to ensure the achievement of the following objectives: 1. In-depth knowledge of the main methods to numerically discretise a mathematical model and to translate it into a system of algebraic equations. This is accomplished by test a). 2. Ability to implement in MATLAB(r) the numerical models presented in class. This is mainly established through test b), but also through test c). 3. Ability to apply the numerical tools to the simulation of the behaviour of physical problems of simple thermodynamic interest. This is establishes through test c). As for the module on advanced engineering thermodynamics, the exam is oral and is conducted as follows. Each student will have to answer a first question on a theoretical topic discussed during the semester. The answer to the first question is written and discussed immediately afterwards through a direct interaction with the examiner, so that it is possible to assess that the student has correctly learned the fundamentals of thermomechanical continuous media, thermodynamics, fluid dynamics as well as environmental acoustics and lighting. This part will last about fourty five minutes with no educational material allowed. Subsequently, the student will have to demonstrate that he/she has actively contributed to the group project, answering a second oral question by the examiner. Here, by focussing on a realistic energy conversion system, it is possible to assess if the student correctly developed sufficient skills for thermal, energy, exergy analysis of energy conversion devices. Alternatively, at the choice of the examiner, this second question may possibly focus on the applied acoustics part. About thirty minutes will be given to reply to the second question. During this part, it is allowed the use of educational material. A partial score for the advanced engineering thermodynamics module only is established, which is given by the arithmetic mean of the marks assigned by the examiner to the first and second answers. Consistently with the expected learning outcomes, the oral part of the exam aims to ensure the achievement of the following objectives: 1. In-depth knowledge of the theoretical notions on thermo-mechanics, continuum theory and thermodynamic. This is accomplished by the first theoretical question; 2. Ability to use the theoretical tools provided in the subject energy and exergetic design and analysis to study real/complex systems involving energy transformation processes. This is established both through the first theoretical question and through the implementation of the group project; 3. Ability to properly interpret the regulations and to perform estimates in the field of lighting and applied acoustic. This is mainly determined by the implementation of the group project and the report on applied acoustic.

Ability to implement in MATLAB(r) the numerical models presented in class. This is mainly established through test b), but also through test c). 3. Ability to apply the numerical tools to the simulation of the behaviour of physical problems of simple thermodynamic interest. This is establishes through test c). As far as the module on advanced engineering thermodynamics is concerned, the onsite examination will follow the exact same procedure as already described in the section on the blended mode with the difference that the first part of the exam shall be held onsite in a dedicated classroom or in a VLAIB.

Advanced engineering thermodynamics/Numerical modelling (Numerical modelling)

The exam consists of both a written part, related to the module of Numerical Modelling, and an oral part, related to the module of Advanced Engineering Thermodynamics. The final evaluation of the exam consists of the arithmetic mean (rounded up) of the two partial scores obtained in the two modules. With regards to the module on Numerical Modeling, the evaluation procedure is based on the following tests: a) solving some exercises on the main topics covered in the module (available time: 60 minutes), b) answering a series of multiple-choice questions with the help of MATLAB using the Exam platform (available time: 45 minutes). No educational material is allowed in these tests. The mark of the written part will also take into account c) the optional preparation of a computational project during the semester, carried out by small groups of students on a numerical topic related to the group project developed in the advanced engineering thermodynamics module, and evaluated on the basis of the individual contribution. Tests a) and b) have a relative weight of 2/3 and 1/3, and overall they allow the sudent to obtain up to 28 points, whereas the computational project allows the student to obtain a higher mark than 28, including the laude. The mark of the written part will be communicated to students through the Portale della Didattica, together with the indication of when and where they can meet the teacher and check the results of their tests. Consistently with the expected learning outcomes, the written part of the exam aims to ensure the achievement of the following objectives: 1. In-depth knowledge of the main methods to numerically discretise a mathematical model and to translate it into a system of algebraic equations. This is accomplished by test a). 2. Ability to implement in MATLAB(r) the numerical models presented in class. This is mainly established through test b), but also through test c). 3. Ability to apply the numerical tools to the simulation of the behaviour of physical problems of simple thermodynamic interest. This is establishes through test c). As for the module on advanced engineering thermodynamics, the exam is oral and is conducted as follows. Each student will have to answer a first question on a theoretical topic discussed during the semester. The answer to the first question is written and discussed immediately afterwards through a direct interaction with the examiner, so that it is possible to assess that the student has correctly learned the fundamentals of thermomechanical continuous media, thermodynamics, fluid dynamics as well as environmental acoustics and lighting. This part will last about fourty five minutes with no educational material allowed. Subsequently, the student will have to demonstrate that he/she has actively contributed to the group project, answering a second oral question by the examiner. Here, by focussing on a realistic energy conversion system, it is possible to assess if the student correctly developed sufficient skills for thermal, energy, exergy analysis of energy conversion devices. Alternatively, at the choice of the examiner, this second question may possibly focus on the applied acoustics part. About thirty minutes will be given to reply to the second question. During this part, it is allowed the use of educational material. A partial score for the advanced engineering thermodynamics module only is established, which is given by the arithmetic mean of the marks assigned by the examiner to the first and second answers. Consistently with the expected learning outcomes, the oral part of the exam aims to ensure the achievement of the following objectives: 1. In-depth knowledge of the theoretical notions on thermo-mechanics, continuum theory and thermodynamic. This is accomplished by the first theoretical question; 2. Ability to use the theoretical tools provided in the subject energy and exergetic design and analysis to study real/complex systems involving energy transformation processes. This is established both through the first theoretical question and through the implementation of the group project; 3. Ability to properly interpret the regulations and to perform estimates in the field of lighting and applied acoustic. This is mainly determined by the implementation of the group project and the report on applied acoustic.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.

Module of Advanced Engineering Thermodynamics. Each student will be given an online test sub-divided in two parts on her/his computer via the Exam+Respondus platform. Each test includes a number of both open-ended and closed-ended questions and the navigation through questions is free. In addition, each student will also be assessed on the result of the group's project and the applied acoustics report. It is permitted to have and use only a few blank A4 papers, a pen (black or blue) and if needed a physical calculator as a possible support during the answers (provided that during the environmental recording and the subsequent use they are all clearly showed in the webcam). It will be possible to close the exam and finish only if at least 90% of the total time has elapsed. The Virtual Classroom integrated in the Exam platform will be also enabled to allow possible interaction with the lecturers. More specifically, the exam of this module is structured in three parts as follows: 1.The first part will include a maximum of 15 open- and/or closed-ended questions that will focus on the fundamental parts of the course, and which aim to assess that the student has correctly understood the theoretical foundations underlying the continuum thermo-mechanics, thermodynamics, heat transfer, applied acoustics and lighting technology discussed during both theoretical and practise lectures. During this first part, using support materials of any kind is strictly forbidden. The maximum time available to complete this part will be at least 40 minutes. The final result of this part will be evaluated up to a max of 15 points. 2. In the second part of the online test, the student must demonstrate that she/he has actively contributed to the group project as well as to the implementation of the applied acoustic report. To this end, a maximum of 12 open- and/or closed-ended questions will be given to each student. The questions will be focused on the design aspects addressed in the specific group work and will aim to assess that the student has understood the use of the tools illustrated in the course for thermal analysis, energy and exergy analysis of processes/systems, as well as the most important aspects of the applied acoustics report. During this part, the support of the group project and the applied acoustic report is allowed. The maximum time available to complete this part will be at least 40 minutes. The final result of this part will be evaluated up to a max of 12 points. 3. Each team must deliver a pdf copy of both the group’s project and the applied acoustics report at least one week before the exam date. Pdf upload must occur through the Teaching Portal, uploading a single PDF file (which contains both the files) in the section "Elaborati". The upload of the file should be performed only by one representative for each group, taking care to report the names, surnames of each group member on the first page of the report. The reports will be evaluated at most 6 points, and the score will be applied to each of the group members. The final mark of the Advanced topics of Engineering Thermodynamics module will be calculated for each student by summing up the scores of the first online part, the second online part and the evaluation of the project reports. The maximum score will be 30 (possibly cum laude if a total grade exceeding 30 points is achieved). Whenever needed, the upper-rounded rule will be used. The Advanced topics of Engineering Thermodynamics module is considered passed if the final score is at least 18 and both reports have been delivered by the group. The final mark will be communicated by the lecturer a week after the exam date, specifying the contribution to the final score of each part of the exam (online part and report evaluation). Consistently with the expected learning outcomes, the exam aims at assessing the achievement of the following objectives: 1. In-depth knowledge of the theoretical notions on thermo-mechanics, continuum theory and thermodynamic. This is accomplished by the first set of online questions; 2. Ability to use the theoretical tools provided in the subject energy and exergetic design and analysis to study real/complex systems involving energy transformation processes. This is established both through the second set of theoretical questions and through the implementation of the group project; 3. Ability to properly interpret the regulations and to perform estimates in the field of lighting and applied acoustic. This is mainly determined by the implementation of the group project and the report on applied acoustic. This is accomplished by the implementation of the group reports. Module of Numerical Modelling. The exam is based on the following tests: a) solving some exercises on the main topics covered in the module (duration 35 minutes); b) answering, using MATLAB(r), a series of multiple choice questions (Duration 40 minutes). It is not allowed the use of any support materials during these tests. In the formulation of the mark, possibly we will take into account also the: c) optional preparation of a computational project during the semester, carried out by small groups of students on a numerical problem linked to an applied project of the module of Advanced Engineering Thermodynamics, and evaluated on the basis of the individual contribution of each student. Tests a) and b) have a relative weight of 2/3 and 1/3 and are provided to reach up to 28 points, while test c) enables to go beyond 28, including “cum laude”. The marks obtained in the written tests will be communicated to the students through the Teaching Portal, together with an indication of when and where the students can view their tests. In the fully remote mode, tests a) and b) are carried out through video surveillance by the teachers: students enter small groups in a certain number of Virtual Classroom activating microphone and webcam, and are followed by a teacher during the exam. At the end of the test a), students upload the written paper on the University platform intended for this purpose. To perform the test b), the students carry out the necessary calculations with Matlab on their computer, by accessing the Exam platform to receive the questions and enter the answers. Finally, test c) is carried out by uploading a paper containing the results of the project and the corresponding teacher-student discussion held on Virtual Classroom. Consistent with the declared learning outcomes, the written part aims at assessing the achievement of the following objectives: 1. Knowledge of the main discretization methodologies of mathematical models and their translation into algebraic equation systems. This is established through test a). 2. Ability to implement the studied numerical models in the MATLAB environment. This is established mainly through test b), but also through test c). 3. Ability to apply the numerical tools studied to the simulation of the problem of engineering thermodynamics problems. This is established through test c). Finally, it should be noted that the mark obtained in the Advanced topics of Engineering Thermodynamics module shall be averaged with the mark obtained in the Numerical modelling module. The upper rounded arithmetic mean of the two modules will be officially recorded as a final grade.
