Abstract

Computational Fluid Dynamics (CFD) was used to simulate the flow field of gas-liquid Taylor flow in circular capillaries. The separate influence of gas bubble velocityVb,Taylor unit lengthLUC, film lengthLfilmand liquid film thicknessδfilmon both the liquid slug velocityVx,topand film velocityVx,filmwere investigated. The values ofVx,topare mainly dependent onVbandδfilmwhileVx,filmrelies on all the four parameters.
