摘要： 基于气固两相流体动力学模型、颗粒动力学理论的颗粒脉动动能（KTGF）和气体湍流动能模型（SGS），对气固两相垂直上升流动进行数值计算，模拟计算结果得到了与试验研究所揭示的环—核流动结构。模拟计算与Miller和Gidaspow（1992）试验结果进行了比较，颗粒相浓度、速度和颗粒相动力粘性系数分布与试验值基本吻合。

Abstract: Solid velocity, particle concentration and solid viscosity are computed in a vertical riser using a two-phase computational fluid dynamic model combination with the solid turbulence kinetic energy model based on the kinetic theory of granular flow (KTGF) and SGS (Subgrid scale) turbulence model for gas phase. The model predicts a coreannular flow structure in a riser, similar to that agree well with the experimental data of Miller and Gidaspow (1992).

Key words: Gas-solid two phase flow, Kinetic theory of granular flow, Numerical computation, SGS model
