Dynamics of gas-liquid interfaces in high-pressure systems (INVITED)

Abstract eng:
This paper summarizes recent theoretical work aimed at explaining the dynamics of gas-liquid interfaces in high-pressure sys- tems. Imaging has long shown that at certain high-pressure conditions, the presence of discrete two-phase flow processes becomes dimin- ished. The molecular gas-liquid interface is replaced by a diffusion dominated shear-layer that evolves in the presence of exceedingly large but continuous thermo-physical gradients. Analysis reveals that the two-phase interface breaks down not necessarily because of vanishing surface tension forces, but because of thickened interfaces in a state of nonequilibrium due to the presence of thermal gradients and an inherent reduction in the molecular mean free path.
