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 ,数值模拟对进一步的研究有指导意义
Based on the kεAp model of gas-solid flow, the gas-solid two-phase flow in the upwardly-upwardly-jetting suspended bed was numerically simulated and the distributions of particle phase velocities and pulsation velocities of the cross sections at different inlet velocities were obtained. Experimental qualitative consistent. The results of calculation and experimental results show that numerical simulation is instructive for further research
