| 摘 要： | 本文采用了内嵌边界多重直接力算法全尺度计算研究了三维空间中颗粒群在重力作用下沉降时,颗粒群与流体之间的相互作用过程。结合多相流的欧拉-欧拉双流体模型方法中对颗粒群与流体之间相互作用力的处理方式,分析了颗粒与流体之间的相交换量。并把全尺度计算得到的颗粒群与流体之间的相交换量与本文中提到的单颗粒受力模型(SPM)和颗粒群受力模型(GPM)对相互作用力进行了比较分析。

| Abstract: | The force interaction between the fluid and the settling particles are studied with the immersed boundary method.The magnitude of the force interaction between the fluid and the settling particles is analyzed in the framework of the Euler-Euler two-fluid model.The force interaction results obtained from the fully resolved simulation are compared with the force model of single particle (SPM) and the force model of group particles(GPM) in the Euler-Euler two-fluid framework. |
