Theoretical thermodynamics


The modelling of the behaviour of macroscopic natural (physical, chemical, biological, …) systems which evolve far from equilibrium forms the object of Thermodynamics of irreversible phenomena. This area of study provides the unifying and appropriate theoretical framework for developing the means of analysis of fluids and solids in very diverse situations. As such, it is often an essential tool of astrophysics, geophysics and oceanography when, for instance, one wants to describe thermoconvection in the stars, the displacements and deformations of the earth's crust or the ocean currents and movements of the atmosphere.

The research conducted by the group of Thermodynamics of irreversible phenomena (TPI) concerns first the theoretical foundations of the study of systems evolving far from equilibrium and, secondly, various applications of this theory. Among these are the thermoconvective motions which can appear in fluids and the resulting self-organizing phenomena. In another area, one can also mention the physical and mathematical description of the cardiovascular system.
