Abstract

The progress of numerical simulation for high entrained gas-liquid two phase flow were summarized and analyzed. The results show that the Euler-Euler method is the most suitable for the air-water two-phase flow. The advantages and disadvantages of three multiphase flow models (VOF, Mixture and Eulerian model) are analyzed and the results show that the Eulerian model is most popular and accurate for simulation the strong turbulent air-water two-phase flow, especially needing to consider the conversion of continuous and discrete phase. The coupled Eulerian model and mixture turbulence model is the best choice for simulation the flow field on the strong air entrained flow in hydraulic engineering.
