气-固两相流边界层双向耦合模型及其应用

Development and Application of Two-way Coupling Model of Gas-par ticle Two-phase Flow Boundary Layer

本文提出了一种稀相的气-固两相流边界层的双向耦合模型,在对固壁附近的粒子源项作了特殊处理后,利用此模型研究了流经平面叶栅的气-固两相流中的固体粒子穿越边界层时受到的影响以及粒子存在对边界层内气体流动的反影响。其中粒子运动特性的计算结果与试验进行了对比分析。

This paper presents a two-way coupling model of dilute gas-particle two-phase flow boundary layer. The particle source term is treated specially near the boundary. The model is applied to predict the interaction of gas-phase and solid phase in the boundary layer of gas-particle two-phase flow through cascades.
