2022/23

The subject aims at providing the students with the basic theoretical knowledge and practical skills needed to face problems related to the performance analysis and the optimal choice of either a thermal or a hydraulic machine. Particular attention will be devoted to the analysis of the design as well as the off-design performance of machines and the power plants.

Turbo-machinery represents a strong topic in the background of a mechanical engineer and the constant attention devoted to the environmental related aspects is to be carefully considered.
The subject hence aims at providing the students with the basic theoretical knowledge and with the practical skills needed to face problems related to the performance analysis and the optimal choice of either a thermal or a hydraulic device. The first part of the subject focuses on a quick review of the Thermodynamic and Fluid Mechanic principles, with specific reference to aspects that are mandatory for the analysis of fluid machines and energetic systems. Particular attention will also be devoted to the analysis of the design as well as the off-design performance of machines and to the design and off-design behavior of power plants.

The first part of the subject focuses on a quick review of the Thermodynamic and Fluid Mechanic principles, with specific reference to aspects that are mandatory for the analysis of fluid machines and energetic systems. Through the systematic application of the thermo-fluid-dynamics principles to energy systems and their components, the module provides the students with the ability to design turbomachines, engines, fluid-power systems and engineering-plant solutions in relation to their applications.

Through the systematic application of the thermo-fluid-dynamics principles to energy systems and to their components, the module provides the students with the ability to:
• design turbo-machines, engines and fluid-power systems;
• design engineering-plant solutions in relation to the specific application;
• tackle issues related to off-design performance;
• tackle issues related to maintenance problems.

In order to fruitfully attend the subject, the student should have previously acquired the basic knowledge of Fluid Machines theory, Thermodynamics, Thermo-kinetic, Applied Mechanics and Fluid Mechanics.

In order to fruitfully attend the subject, the student should have previously acquired the basic knowledge of:
• Fluid Machines theory;
• Thermodynamics;
• Thermo-kinetic;
• Applied Mechanics;
• Fluid Mechanics.

Syllabus
• Introduction to fluid machines. Review of the thermodynamics and fluid-dynamics applied to fluid machines. Velocity diagrams, Euler work equation.

The subject is made up of lectures and applied lectures. The applied lectures consist of exercises meant to further deepen the understanding of the concepts dealt with within the lectures.

The subject is structured as follows:
• 70 hours of lectures, devoted to the development of the basic knowledge on the design and performance of thermal and hydraulic machines.
• 30 hours of applied lectures, meant to stimulate the acquired competences and to consolidate them through the solution of exercises. These latter will allow the students to further deepen the understanding of the concepts dealt with within the lectures.
Tutoring hours might also be foreseen depending on the arrangements of the academic year.
Laboratories: lab activities will also be possibly integrated into the course structure. Still, due to logistic issues, these latter will only be offered to the students officially attending the course for the first time. Reports will be eventually required and will contribute to the exam final mark as described in the following section.

Exam rules
The exam booking on the web portal, within the deadline, is mandatory.
The exam is made up of a written test and of an oral test. The final mark is the average of the marks achieved for the written and the oral parts.
Written test (duration: 2 h 30 min)
The written test aims at evaluating the students’ competences in terms of formula application and problem solving.
The student is asked to solve 2 exercises featuring a difficulty level similar to that of the exercises proposed during the applied lectures. Each exercise sums up for 15 points out of 30.
During the written test, the student are only allowed to use a scientific calculator, the steam Mollier chart, the saturation tables and a formulary, to be written on a A4 paper and to be prepared by the students. The use of notebooks, smart phones, cell phones or any other electronic device is strictly forbidden. Should any candidate use any un-authorized electronic devices (regardless if it is switched on or off, online or offline), he/she will be immediately withdrawn from the exam.
The paper sheets for the exam will be provided by the teacher. Each sheet has to be returned at the scheduled hand-in time or at the exam withdrawal.
The candidate can withdraw from the written test at any time up to the hand-in time. In this case, the exam failure will not be registered. Once the written test has been corrected, the exam will be registered with either a positive or negative result.
Any candidate who is not satisfied with the written test result can ask to be failed before the oral start.
Oral test
The oral test aims at verifying on a deeper basis the acquired theoretical and practical oriented knowledge.
During the oral exam, the students will be required to prove his/her knowledge on the subject basics (definitions, demonstrations, equations) as well as to be able to deal with problems derived from practical applications. The oral test is mandatory and will deal with the topics dealt with within the lectures.
The oral test can be accessed only provided that a minimum score of 12/30 is achieved in the written test.
A failure in the oral test will lead to the exam failure.

Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.

The exam outcome might possibly increase up to 4 marks if all of the followings apply:
• the student has successfully passed the written and the oral test;
• the student is attending the course for the first time in his academic career (no prior attendance);
• the student has attended the above-mentioned lab activities and handed in the required reports within the due dates.

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.
