摘要: 应用两相流动力学理论,对旋流场内分散相颗粒的受力进行了全面的分析,并将诸力划分为确定性的作用力和随机性的作用力两个部分。在此基础上,建立了分散相颗粒随机运动微分方程,为进一步深入认识旋流场内分散相颗粒的运动行为奠定了基础。

关键词: 旋流场, 颗粒, 受力特性, 随机运动微分方程

Abstract: The forces acting on the dispersal particles in a swirling flow field are analyzed in an all-round way by applying the theory of two-phase flow dynamics, and the relevant forces are classified into definitive forces and stochastic forces. On this basis, a differential equation of the stochastic motion of dispersal particles is established, laying a foundation for the further study of the motion behavior of dispersal particles in a swirling flow field.
