采用硬球模型描述颗粒间的碰撞作用。
The hard sphere model was used to describe inter-particle collisions.
团聚室中引入气固射流，使团聚室内形成局部湍流，强化颗粒间的碰撞。
In order to intensify the collision among the inhalable particles, a gas-solid jet flow was introduced into the agglomeration chamber to generate a local turbulent flow field.
计算结果表明颗粒间非弹性碰撞和气固间曳力的增大均使气固两相流动的非均匀性增大。
The results show that the stronger the particle-particle collisional dissipation and gas-solid drag force, the more heterogeneous the flow structure.
在离散颗粒模型中，根据对颗粒间碰撞过程的处理方法的不同可分为确定性模型和随机性模型。
