# Thermodynamics - fundamentals and applications

## Presentation

Programme (detailed contents):

Fundamental concepts (concept of systems, evolution of a system, mathematical tools in thermodynamics, ideal gas model). Work and heat. The first law of thermodynamics and the internal energy function. The enthalpy function and the steady-state systems. Thermodynamic functions changes during reactions. Physical equilibria for a pure substance (Gibbs function, phases diagram, real fluids). Thermodynamic machines (enthalpy and entropy diagram, power plants, refrigeration units and heat pumps).

Organisation:

-  E-learning platform containing the slides of the lectures, the content of the practicals and self-assessment questionnaires on each chapter

-  Lectures focusing on the basics;

-  Tutorials illustrating and applying the concepts presented during lectures and promoting dialogue between learners and trainers;

-  Written framework consisting of problems with partial answers guiding the individual work of students;

-  Practicals.

Main difficulties for students:

Related to the specificity of thermodynamics. It is an essentially inductive and deductive science; it takes time and needs a regular work to be assimilated.

## Objectives

At the end of this module, students should have understood and be ableto explain :
- the inductive approach, specific to thermodynamics, which is to generalize, by
defining them as laws, the conditions for energy conservation and evolution of
systems;
- the significance, the relevance and the application domains of the main thermodynamic
functions (internal energy, enthalpy, entropy and Gibbs function).

Students should be able to:
- identify the system under study and to establish, for this system, routinely and
systematically, the material balance, the energy balance and the balance of entropy ;
- use and interpret the enthalpy diagram and the entropy diagram of real fluids ;
- apply thermodynamics to the understanding and description of phase equilibria for
a pure substance;
- explain the operation of thermodynamic machines (power plants, refrigeration unit,
heat pump), based on the two laws of thermodynamics and on phase equilibria.

## Needed prerequisite

Concept of function of several variables and partial derivatives.

## Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
