The course is logically divided in two parts: one is more related to the development of a hands-on attitude for some nuclear-relevant measurements; the second is more theoretical, and related to the problem of removing high heat fluxes from nuclear components.
The course is logically divided in two parts: 1) A part related to the development of a basic theoretical knowledge and some practical skills that would be needed to face the important technical problems in the experimental measurements of the main physical quantities in the energetic and nuclear field; 2) A part related to the problem of removing high heat fluxes from nuclear components, with particular reference to the active cooling by fluids in single-phase, turbulent regime considering the different peculiarities of Prandtl number ranging <1 (liquid metals), ~ 1 (air or He), or >1 (water, molten salts), as well as to the multi-phase flow (liquid/vapor or liquid/solid matrix in a porous medium) .
The students are expected to become aware of techniques and issues in the experiments that concern single phase and two phase pressure drop and heat transfer, and the characterization of materials in nuclear environment, relevant for fission and fusion applications. Furthermore, the acquisition of critical capability to model components or systems characterized by the need for removal of high heat fluxes is expected.
The students are expected to understand, design and carry on experimental activities that concern single phase and two-phase pressure drop and heat transfer, and the characterization of materials in nuclear environment, relevant for fission and fusion applications. Furthermore, the students are expected to become capable to design and analyze complex components characterized by the need for removal of high heat fluxes, using analytical and numerical tools.
Knowledge of thermo-dynamics, single-phase thermal-fluid dynamics, advanced materials for nuclear applications, basic knowledge of operating principles of fission and fusion nuclear reactors. Basic knowledge of programming (in MATLAB) is welcome.

Modalità di esame: Prova orale obbligatoria;
Exam: Compulsory oral exam;
For the individual project: the teachers will evaluate the methodology used to develop the project, its originality and feasibility. The project max score is 24/30. The compulsory oral exam, based on open questions on the course topics, will allow students to round their score to the maximum.
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.
Exam: Compulsory oral exam;
Concerning the first part of the course, a written exam will checks the student knowledge about the capability of selecting a proper transducer in accordance to the characteristics of the physical quantity under investigation, and of configuring the acquisition chain and set the acquisition parameters. The written exam, contributing to the 25% of the final mark, will be divided in two parts, for a total duration of 50 min: - 1st part (15/30): The student has to answer to 5 multiple choice questions (MCQ). 2 MCQs concern to the practical activities developed in the laboratory and 3 MCQs are related to the topics discussed in the lectures. The MCQs can provide more than one correct answers. The evaluation of the MCQ is performed in accordance to the following rules: . +3 points when all the correct answers are selected; 0 points when none or all the answers are selected; -3 points when all the incorrect answers are selected. When a mixed selection of correct and incorrect answers is provided, the evaluation if performed in accordance to the above rules. - 2nd part (mark 15/30): the student has to solve 1 exercise regarding the DAQ setup. For the second part of the course, an individual project will be carried out and presented through a written report, to be uploaded on the course website: the teachers will evaluate the methodology used to develop the project, its originality and feasibility. The project contributes to the 50% of the final mark. The compulsory oral exam, based on open questions on the course topics and discussion of the project, will allow students to round their score to the maximum.
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.
