ON EQUATION OF DISCRETE SOLID PARTICLES’ MOTION IN ARBITRARY FLOW FIELD AND ITS PROPERTIES

Abstract

Abstract: The forces on rigid particles moving in relation to fluid having been studied and the equation of modifications of their expressions under different flow conditions discussed, a general form of equation for discrete particles’ motion in arbitrary flow field is obtained. The mathematical features of the linear form of the equation are clarified and analytical solution of the linearized equation is gotten by means of Laplace transform. According to above theoretical results, the effects of particles’ properties on its motion in several typical flow field are studied, with some meaningful conclusions being reached.

Key words: solid liquid, two phase flow, discrete particles’ motion equation, discrete solid particles, Laplace transform
