| 摘 要： | 本文提出了一种对于气固两相紊流剪切流中圆形固体颗粒弥散的拉格朗日拟计算方法，其中考虑了颗粒间的磁撞对流体相和颗料相的影响，应用该方法对一气固紊流剪切流场进行了模拟计算，并对有、无颗粒间磁撞情况下的模拟计算结果与Lavieville用大涡模拟方法的研究结果进行了比较，并进行了讨论。

| Abstract: | A particle dispersion Lagrangian simulation approach to account for inter particle collisions in gas solid turbulent flows is presented. The proposed model was applied to a gas solid turbulent shear flow. The computed results have been compared with the results of Lavieville by Large Eddy Simulation, and the influence of inter particle collisions has been discussed. |
