Gravity-Modulated Thermo Capillary Convection in a Liquid Bridge
Краткое описание
The problem of thermo capillary convection in a liquid bridge has been studied in a gravity-modulated environment. The half zone consists of a liquid bridge held between two solid, planar end walls across which a temperature gradient is applied. Thus the basic state of thermo capillary convection consists of a single toroidal roll with the surface motion directed downwards from the hot upper disc to the cold lower one. The interface deformation caused by the gravity jitters depends on the volume of the liquid bridge and cause changes in the basic state of the fluid. The deformation of free surface of the liquid column may introduce oscillatory flow field, which may induce convection. The paper discusses the effect of recirculatory flow inside the bridge on the stability of liquid bridges.
