Description

This module completes and formalizes the notions of thermodynamics introduced in EU Thermodynamics 1, by exploring several aspects in greater depth: thermodynamic potentials defined on the basis of Legendre transformations, thermodynamics of open systems, pure-body phase transitions and irreversible processes, with incursions at the microscopic level to provide an insight into the physical foundations of the theory.

Objectives

  • Use differential forms and their properties in thermodynamics.
  • Draw up an energy balance and entropy balance for a compound thermodynamic system.
  • Predict the macroscopic properties of simple physical models (e.g. perfect gas, real gas, harmonic solid).
  • Apply methods for solving ordinary differential equations to thermodynamic problems (e.g. pressure in a compressible fluid).
  • Perform an energy and entropy balance for an open system
  • Integrate a diffusion equation in simple cases.
  • Establish the link between the macroscopic and microscopic description of a system
