稀相气—固两相流在铅垂圆管中的流动特性

Flowing Feature of Gas-solid Two-phase Flows of Sparse Phase in Vertical Circular Pipe

在国外对气-固两相流进行了广泛的实验研究基础上,本文从连续介质理论出发,分别讨论了两相流中的气体与固体颗粒的基本方程。给出了在铅垂圆管中一维两相流动的基本方程,并进行了数值求解和理论分析。

On the basis of experimental studies done abroad of gas-solid two-phase flows,this paper discusses the fundamental equations of the gas and the solid particle of two-phase flows respectively in accordance with the theory of continuous medium. It gives the fundamental equations of onedimensional two-phase flows in vertical circular pipe and their numerical solutions. Finally theoretic analyses are made.
