This article presents a general introduction to the thermophysical and dynamical properties
of supercritical fluids. It is organized in two parts: in a first section, the nature of the critical …

Heat transfer via acoustic waves, known as adiabatic thermalization or the piston effect, was
previously studied in enclosures under microgravity and terrestrial conditions with carbon …

Recent advances in the knowledge of heat transport near the liquid-gas critical point under
the influence of the piston effect are reviewed with an emphasis on the different physical …

Heat transfer inside microscale geometries is a complex and a challenging phenomenon. As
supercritical fluids display large variations in their properties in the vicinity of the critical …

We experimentally investigate natural convection of a supercritical nitrogen/argon (0.9/0.1 in
molar fraction) binary fluid in a bottom-heated cavity with an aspect ratio of 2.5 in the present …

Near the thermodynamic critical point, the physical properties of binary fluids exhibit large
variations in response to small temperature and concentration differences, whose effects on …

The nonlinear oscillatory double-diffusive convection in a thermodynamically near-critical
binary fluid layer is investigated to explore the interactions between the piston effect and …

Thermomechanical effects, ie, Piston effect (PE), Soret effect (SE), and Dufour effect (DE),
occur in supercritical binary fluids when subjected to boundary thermal perturbation due to …

A linear stability analysis is conducted for the onset of natural convection driven by a
concentration gradient in a horizontal layer of a near-critical binary fluid mixture. The …

Chemical reactions at high pressures are widely used in modern technology (supercritical
extraction is an example). On the other hand, critical phenomena is the more advanced field …
