Abstract

Hydrodynamics of near-critical fluids have gained considerable interest since the identification of the thermo-acoustic effect, an effect responsible for a fast thermal equilibration in a cell heated at one boundary [1, 2, 3]. Transport coefficients exhibit strong deviations near the critical point (CP). They are characterized by large density (alike a liquid) and low viscosity, large compressibility (alike a gas). When nearing the CP, some properties (compressibility, thermal expansion, thermal conductivity, specific heat capacity) diverge while others (thermal diffusivity, surface tension) go to zero.
