Non-Equilibrium Meso-Thermodynamics of Fluid Phase Separation

6 Non-Equilibrium Meso-Thermodynamics of Fluid Phase Separation 

The concepts of meso-thermodynamics can be extended to some non-equilibrium phenomena. In particular, like the thermodynamic properties, transport coefficients, such as the diffusion coefficient, become spatially dependent at meso-scales. Moreover, away from equilibrium, generic long-range correlations emerge even in simple molecular fluids, making the famous concept of local equilibrium, at least, questionable. In this section we focus only on one application of mesoscopic nonequilibrium thermodynamics in fluids fluid phase separation.
