| 中文摘要: |
| 在均匀，稳定的各向同性气固两相紊流场颗粒弥散的拉格朗日模拟计算方法基础上，进一步考虑了流场中颗粒之间的碰撞对于模拟计算结果的影响。与Lavieville用大涡模拟所做的计算结果进行了对比，以对本方法进行验证，并考察了颗粒间的碰撞分别对流体相和颗粒相的影响。 |
| 英文摘要: |
| A simulation approach of particle to particle collisions, based on a particle Lagrangian technique simulation technique in homogeneous, stationary and isotropic gas solid turbulent flows, is presented. This model has been used to simulate a homogeneous gas solid turbulent dlow. Comparisons are made with the computed results of Lavieville used by Large Eddy Simulation to verify the approach, and the influence of inter particle collisions on the fluid and particle phases is investigated. |
