摘要

阐述了幂律流体控制方程的特点，研究了幂律流体的稠度系数和流动指数的变化对两相流动的影响.随着流动指数的增加，幂律流体在圆管中心附近的主流速度减小，同时颗粒相速度在圆管中心附近增大，而在管壁附近减小.随着稠度系数的增加，幂律流体和颗粒相的主流速度分布出现了与流动指数带来的影响相似的趋势.对带颗粒的幂律流体的两相流流动与液固两相流流动做了比较，幂律流体两相流的流体速度在管道中心附近的大部分区域比液固两相流的流体速度流动的速度大，而颗粒相的速度分布比较平坦.

Abstract

The characteristics of power law fluid governing equation was elaborated and the effect of viscosity and flow exponent on two-phase flow was studied. With increasing flow exponent

the velocity of power law fluid near the pipe center decreased

and the velocity of particle near the pipe center increased but decreased near the pipe wall. With increasing viscosity

the velocities of power law fluid and particle showed the same trend. It was found be compared the two-phase flow of power law fluid-solid with that of liquid-solid that the fluid velocity of power law fluid-solid was bigger than that of liquid-solid and the particle velocity distribution of power law fluid-solid was flatter than that of liquid-solid.
