Exact analytical solutions for the piston effect in supercritical fluids under post-acoustic approximation -- Short-time asymptotics, thermal penetration depth and comparison with the Spacelab D-2 experiments
Mátyás Szücs, Mátyás Szücs
Near the liquid-vapor critical point, fluids become highly compressible, giving rise to a special, strongly coupled thermo-mechanical process: the piston effect. In this phenomenon…

Thermodynamic compatibility, holographic property and wave-function representation of generalized weakly nonlocal self-gravitating non-relativistic fluids
Mátyás Szücs, Péter Ván
A thermodynamic analysis of weakly nonlocal non-relativistic fluids is presented under the assumption that an additional scalar field also contributes to the dynamics. The most gen…

The piston effect in supercritical fluids investigated via a reversible-irreversible vector field splitting-based explicit time integration scheme
Donát M. Takács, Tamás Fülöp, Róbert Kovács +1
In the vicinity of the liquid--vapor critical point, supercritical fluids behave strongly compressibly and, in parallel, thermophysical properties have strong state dependence. The…
