摘要
从气固流动的kεAp 模型出发 ,对底部向上射流悬浮床内气固两相流动进行了数值模拟 ,得到了不同入口气速下各截面的颗粒相速度场和脉动速度场的分布 ,计算结果与实验定性一致。计算结果与实验值对比的结果表明 。
Starting from the K-ε-Ap model of gas-solid flow,a numerical simulation for two-phase gas-solid flow in the suspension bed composed of bottom-up ejected fluid has been carried out, the distribution of particles' phase velocity field and pulsation velocity field at every cross-section under various inlet gas velocity are obtained, the calculation results being consistent with the qualitative analysis by experiment. The results of comparing calculation and experiment values show, the numerical simulation has significance for guiding further research work.
