Numerical study on thermocapillary convection in liquid bridge under surrounding shear gas stream
Key Laboratory of National Education Ministry for Electromagnetic Processes of Materials, Northeastern University in Shen Yang, China
In this paper, a numerical simulation on the flow of liquid bridge and gas flow channel has been conducted to analyze the effect of airflow velocity on the isothermal liquid bridge free surface and the flow pattern in liquid bridge. The results show that the different pressure makes the lower part of liquid bridge shrink but makes the upper expand for the silicone oil liquid bridge of volume ratio V = 1, aspect ratio τ =1. It will cause volatility in surface when shear gas stream just acting on the free surface of liquid bridge. When the shear gas stream acting on the free surface lasts 0.14s, the fluctuation of free surface reaches a steady state, and the fluctuation of surface is less than 0.5μm. In the process of free surface wave, the maximum value of deformation usually appears in the bumps or the pits, and the deformation of the point near z = d / 2 is always zero.
