Content
  1. Kinetic approach. Presentation of the Maxwell-Boltzmann kinetic theory of gases. Relations between mascroscopic variables and kinetic theory. Derivation of principal transport coefficients (viscosity coefficient, conductivity, diffusivity), state equations, thermodynamic functions and their derivatives (internal energy, specific heats, entropy). Limits of continuum theory (rarefied gases, plasma). Study of specific problems in liquids (macromolecules) and solids (plasticity).
  2. Continuum approach. Summary of equilibrium thermodynamics: first thermodynamic axiom (principle of energy conservation), absolute temperature and entropy, second thermodynamic axiom, thermodynamic potentials, thermochemistry and electrochemistry, Gibbs relations, equation of Gibbs & Duhem, phase transitions, interfaces.
  3. Classical theory of irreversible thermodynamics (linear theory of Onsager-Prigogine): local equilibrium, entropy production, thermodynamic fluxes and forces, reciprocal relations, evolution laws and constitutive relations. Stationary states: criteria for minimum of entropy production and minimum of dissipated energy. Couplings between thermal, mechanical, and electromagnetic phenomena: thermoelectric and thermomagnetic effects.
  4. Introduction to modern theories. Rational thermodynamics: material memory, objectivity, Clasius-Duhem inequality, constitutive relations. Applications in Non-Newtonian fluids and viscoelastic materials. Extended irreversible thermodynamics: basic hypotheses, causality, application in thermal conduction, second sound, comparison with the linear theory of Onsager-Prigogine.
