| 摘 要： | 在ＤＩＰＳＡＲ算法的基础上，推导了适用于可压密相气固两相湍流流动数据会计的ＣＤＩＰＳＡＲ算法，利用提出的可压密相的两个ｋ－ε低湍流雷诺数模型，用ＣＤＩＰＳＡＲ算法，对竖直上升管中可压密相气固两相湍流流动进行了数值计算，同时考虑了密度变化和体积分数变化的影响，研究结果表明，随着颗粒体积分数的增加，颗料间及颗粒与壁面间的相互作用占了主导地位，使得单个颗粒脉动速度增大，但是气体及颗粒的速度差却随之减小，

| Abstract: | A CDIPSAR algorithm on compressible and dense gas solid two phase turbulent flow is developed. A low Reynolds number model is first presented and a numerical computation for dense gas solid two phase up flow in a pipe is performed. The influence of density and volumetric fraction of particles is considered. It is showed that the forces among the particles and between the particle and wall are dominant with the increase of volumetric fraction, while velocity difference between gas and particle is decreased; and two phase turbulent flow appears intensively anisotropic property. |
