Course Curriculum CFU Length(h)


The course is designed to provide the knowledge and skills with respect to the following topics:
Theoretical aspects
What quantities, laws, and principles define and influence a complex thermodynamic system?
The laws of the thermal radiation exchange.
The laws of heat transfer, multidimensional, transient, and steady-state conduction, convection, and thermodynamic effects related to their interactions with the matter.
Fundamentals on Energy and Exergy analysis in order to get the basic concepts to evaluate the efficiency and the energy performances for the energy conversion systems in all its forms.
Applied knowledge to be able to :
1) generate the right thermodynamic framework for the systems in exchange conditions of heat, radiation, work, and flow mass, as a result of the application of the thermodynamics principles;
2) evaluate the conversion efficiency of the complex thermodynamic systems
3) design materials with respect to their thermo-technics proprieties in order to get the specific thermodynamic conditions under conduction, convection, and radiation heat transfer.

Teaching Methods

Due to the spread of the Covid-19 disease, a specific teaching approach could be necessary to guarantee the social distancing measures. To this end, the teaching activity should be accessible "in presence" and simultaneously also by online mode. Therfore, each student may to opt , if attending the lessons in the presence or at online mode.
In particular, teaching activity will be prevalently performed in presence, integrated and enhanced by using onliine strategies, in order to guarantee its use in an innovative and inclusive way.

INTRODUCTION TO THERMODYNAMICS(theory: 4 hours, exercises: 1 hour)
HEAT AND thermal RADIATION (theory: 8 hours, exercises 6 hours)
THERMODYNAMICS OF OPEN SYSTEM (theory: 4 hours, exercises 2 hours)
FUNDAMENTAL THEOREMS - (theory: 4 hours, exercises 1 hours)

Verification of learning

Final exam and scoring Method:
Verification of the learning process consists of a written and oral test.
Both tests are aimed at determining the student's ability in formulating the correct thermodynamic framework of a physical problem in which heat exchanges by conduction and convection, radiation, work, and mass drive a thermodynamic process of a given system. The correct formulation should be developed accordingly to the thermodynamic laws with the aim to establish the quantitative relationships between the heat and the radiation exchanges, the work done and the evolution of the thermodynamic coordinates that describe the state of a system.
The written test consists in carrying out 6 punctual questions concerning all the topics covered in class.
Two of six are theoretical questions:
They concern the statements of the thermodynamic principles, the cardinal theorems, the description of the mechanisms and laws of heat and radiation exchange, and in general all the remarkable results achieved through purely theoretical demonstration.
Four of six are exercises on numerical applications prevalently concerning the following aspects.
a) numerical applications on the use of the first and second thermodynamic law for closed and open systems.
b) calculations of the internal state quantities: variations of the internal energy, enthalpy, and entropy rising from reversible and irreversible processes caused by the exchange of work, heat, radiation, and mass.
c) numerical analysis of the energy conversion processes performed by the prime mover and refrigeration machines. Conversion efficiency and irreversibility analysis.
d) evaluation of heat and temperature distribution in problems based on the presence of both simple and combined heat exchange mechanisms.
Scoring Method
A score ranging from zero to six can be assigned to each question of the "written test".
As concerning the written part of the test, the perfect score (30, 30 with honors) can be achieved if five answers among the six proposed are right and exhaustively presented
The answers that are not supported by an adequate theoretical and /or numerical justification may not be judged with a full score.
The oral test can be only taken after passing the "written test". It consists of a series of questions, (maximum three), aimed at verifying the mastery of some specific topics that are already developed in response to the 6 questions of the "written test", or even in verifying some aspects of the "written test" that have not received any answer.
A score ranging from zero to three can be assigned to the "oral test".
The overall score will be obtained by summing the score of the "written test" with the score of the "oral test".
