Instantaneous deformation characteristics of a single bubble in immiscible fluids
文献摘要：
The passage of a rising bubble through immiscible fluids is encountered in bath smelting.In order to investigate char-acteristics of bubble deformation in immiscible fluids,the bubble shape change at the interface and the relationship between the bubble aspect ratio(E)and dimensionless number of forces were obtained.A three-dimensional model was established,and the free-floating behavior of a single bubble in immiscible fluids was numerically simulated by phase-field method.The simulation results are in good agreement with experimental results.The results indicate that when the bubble passes through the interface,the bubble shape is divided into four types in turn:"pear",inverted"pear","convex"and"droplet"shape.In the lower liquid,the relationship of E to Weber number(We),Tadaki number(Ta),and Reynolds number(Re)is distributed between two intersecting lines.The relationship of E to E?tv?s number(Eo),a dimensionless group,and Galilei number(Ga)is distributed near the lines with slopes of-3.325×10-5,-0.0855,and-8.73×10-4,respectively.In the upper liquid,the relationship of E to We,Ta,and Re is distributed between two parallel lines.Compared with gravity,the inertial force plays a leading role in the bubble shape in the lower and upper liquid.Compared with the viscous force,the surface tension dominates the bubble shape in the lower liquid.
