CFD of air/water two-phase flow in small horizontal pipe

Yao, Jun; Yao, Yufeng

Abstract

Computational Fluid Dynamics (CFD) has been applied to investigate air/water two-phase flow characteristics in an 8.8mm I.D small horizontal pipe. Simulation has successfully predicted water film thickness using newly developed user defined wave function model. Due to strong gas/liquid interference, liquid film coverage along the top wall of the pipe was thickened resulting in a fully developed annular flow. Compared to the wavy annular flow regime, droplets are found to experience earlier broken at the liquid wavy front when travels from the low wall to the top wall of the pipe. The finding is expected to use in an ongoing industry applications associated with a novel air/water pump design
