为了解微通道内气液两相流型对换热器热质传递的影响，建立了微通道内气液两相流型的数值模型。本文对微通道内气液两相波纹流、环状流和弹状流进行模拟，采用 VOF 界面追踪方法来描述气液相界面，并考虑了表面张力和重力的影响，并建立了预测微通道内气液两相流型的数值模型。通过与已有文献中的实验数据对比，验证了模型的可靠性。

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.
