Turbulent mixing of a slightly supercritical Van der Waals fluid at Low-Mach number [PDF]

, 2014
Supercritical fluids near the critical point are characterized by liquid-like densities and gas-like transport properties. These features are purposely exploited in different contexts ranging from natural products extraction/fractionation to aerospace ...

Soft-wall induced structure and dynamics of partially confined supercritical fluids

, 2019
The interplay between the structure and dynamics of partially confined Lennard Jones (LJ) fluids, deep into the supercritical phase, is studied over a wide range of densities in the context of the Frenkel line (FL), which separates rigid liquidlike and ...
