Lecture notes will be distributed by the teacher. - Educational objectives
- The primary goal of the module consists of providing students with tools to solve advanced heat transfer issues. The laboratory phase is aimed to make visible the theoretical aspects treated in class lectures, both in experimental terms and as far as the use of thermal-fluid-dynamic calculations.
- Prerequisites
- The student must know the basics of mathematical analysis, with particular reference to differential and integral calculation. Essential prerequisites are also the basics of thermodynamics.
- Teaching methods
- The course is organized with classroom on all treated subjects, as well as laboratory exercises for observing the heat transfer phenomena. The study of computational analysis is supported by application examples through a commercial code.
- Other information
- Attendance to the classes is optional but strongly advised.
- Learning verification modality
- The exam includes a written test and an oral exam. The written exam, which lasts 2 hours, is the solution of 4 themes on topics related to the program, chosen within a list provided to the students. The test is intended to verify: i) the ability to understand the problems proposed during the course, ii) the ability to correctly apply the theoretical knowledge, iii) the ability to effectively communicate in writing. The oral tests, one for each module, consist of a discussion of no longer than 45 minutes each aimed to determine: i) the level of theoretical and methodological knowledge of the contents; ii) the independence of judgment in proposing the most appropriate approach for each scope. The oral examinations also aims to verify the student's ability to expose issues proposed by the Commission with property of language, to support a dialectical relationship during discussion and summarize the results of application of the theories studied.
