VOF simulations of gas bubbles motion in a reciprocally stirred flow

摘要：

　　This paper reports progress in the numerical simulations of movement and the coalescence of two neighbor bubbles (leading and trailing bubble) in a reciprocally stirred liquid flow field.The full Navier-Stokes equations are solved by the volume-of fluid (VOF) method for tracking the interface between the bubble and the liquid flow.A dynamic mesh method was used to predict the gas-liquid flow in a two-dimensional foaming tank.Results indicate that the motion and merge behavior of the bubbles is dominantly influenced by the initial locations and the sizes of the bubbles as well as by the surface tension,while the reciprocating effect is insignificant.
