摘要
本文应用一种考虑气体-颗粒湍流相互作用的二阶矩模型对喷管跨音速两相流动进行了数值模拟,研究了改变颗粒直径和载荷比对流动的影响。计算结果和实验数据及前人研究结果相吻合,表明二阶矩模型能够对跨音速两相湍流做出很好地预测。
A second- order moment model, which accounts for turbulence interactions of gas - particle, is firstly employed to numerically simulate transonic two- phase flow in JPL nozzle. The predicted results, which delineate the effects of particle diameter and loading ratio, are in agreement with the data from experiment and previous model. It is shown that the second- order moment model can predict the transonic two - phase flow well.
