Abstract

Abstract

A mathematical model of concentration in a fully developed dilute gas-solid vertical flow was developed by neglecting inert and viscous terms of radius direction.And the existing conditions of some modes of concentration distribution were obtained through the analysis of the model.Based on Hinze-Tchen formula and theory of mixing length,a mathematical model of viscosity of solid phase was gotten,and the factors that affect the viscosity were analysed by the calculation of the model.
