摘要
分析了气固两相湍流在垂直管道内的流动．利用热力学守恒气固两相湍流模型，考虑流体流动为高雷诺数的情况，建立了垂直管道内二维气固两相湍流流动模型．使用ＳＩＭＰＬＥＲ算法，利用气相与固壁无滑移、固相与固壁有微小滑移的条件，计算了一种实际流动，得到了满意的结果．计算结果表明，因为固粒的脉动，使气相的湍流场更加趋于平缓．
A thermodynamically conservative twodimensional turbulent model is proposed and the twophase turbulent flow with high Reynolds number in a vertical duct is calculated by using the SIMPLER algorithm. The no slip and slight slip conditions are applied to the gas and particle phase on the duct wall, respectively. The computational results show that the gasparticle turbulent field is flat in appearance, due to the fluctuation of particles ejected into the gas stream.
