A kinetic model for the study of capillary flows in micromechanical devices has been presented. The model is based on the Enskog-Vlasov kinetic equation and provides a reasonable description of two-phase flows and of fluid-surface interaction. The structure of liquid menisci between two hydrophilic walls has been studied and our results agree fairly well with the Laplace-Kelvin equation. Meniscus breakage has been computed and a possible explanation of the phenomenon has been given.

Abstract

A kinetic model for the study of capillary flows in micromechanical devices has been presented. The model is based on the Enskog-Vlasov kinetic equation and provides a reasonable description of two-phase flows and of fluid-surface interaction. The structure of liquid menisci between two hydrophilic walls has been studied and our results agree fairly well with the Laplace-Kelvin equation. Meniscus breakage has been computed and a possible explanation of the phenomenon has been given.
