| 摘 要： | 基于稠密气体分子运动论和颗粒动理学,建立可压稠密气固两相流动模型。采用梯度模拟来考虑气相可压缩性对气相湍流的影响。模拟计算表明气固两相射流速度沿轴向和径向减小,颗粒浓度下降。气固两相射流具有高的颗粒温度,呈现强烈的气固两相湍流流动特性。

| Abstract: | A two-fluid model of compressible dense gas-solid flow was proposed based on the kinetic theory of dense gases and granular flow concerning with the effect of the compressibility of gas phase. The turbulence of gas phase was modeled by the gradient simulation approach. Simulation results shown that the jet velocities of gas and particle phases, and concentration decreased along both the radial and axial directions. High granular temperature of particles appeared the intensity turbulence of gas-solid jetting flow. |
