摘要
本文从Maxey和Riley的粒子运动基本方程出发,得到了球形固体粒子在相对流动雷诺数很小情形下的分析解。讨论了粒子跟随性对外力、初始条件和流场性质的依赖关系;对均匀湍流场。
According to the particle motion equations given by Maxey and Riley, an analytical solution of the degenerative equation of a sphericai solid particle in very small relative motion Reynolds number is obtained, and the particle following behaviours, which depend on the external force, initial condition and the properties of the flow fileds, are discussed. The effects of the different frequencies and density rates on the flow following behaviours in homogeneous turbulent flow are also analysed.
