摘要
本文总结了颗粒流体两相流基本方程的压差力表达方式和推导颗粒流体系统曳力系数计算公式的力平衡原理，提出了一种分析压差力的简单方法。
Pressure drop in basic eqllations of particle-fluid two-phase flow is reformulated in this paper by coupling the partial pressure of granular flow to the partial pressure of the fluid,resulting in the unification of different formulating approaches used currently.Drag coefficients corresponding to different formulations of pressure drop are also discussed to elucidate the relationship between drag coefficient and pressure formulation.
