Abstract
To know the influence of gas-liquid two phase flow pattern on heat and mass transfer in micro-channel heat exchanger, the numerical model of simulating various two phase flow patterns was established. In this paper, different flow patterns, including stratified flow, taylor flow and annular flow, were simulated employing VOF method in FLUENT solver, and gravity was taken in account in the simulation as well as surface tension. And the numerical model to forecast the two phase flow patterns was established. To compare with the published experimental data, the dependability of the model was validated.关键词
