气固两相流中颗粒弥散的拉格朗日模拟

Lagrangian simulation of particle dispersion in gas-solid turbulent flows

本文提出了一种对于均匀、稳定及各向同性气固两相紊流场中圆形固体颗粒弥散的拉格朗日模拟计算方法 ,应用该方法对带有网栅的垂直与水平管道中均匀、稳定的气固两相流模拟计算结果与 Snyder及 Wells等人所做的相同情况下的试验结果进行了比较 ,以证明该模拟计算方法的有效性。

A particle dispersion Lagrangian simulation approach in homogeneous, stationary and isotropic gas-solid turbulent flows is presented. The computational model was applied to the homogeneous and stationary gas-solid turbulent flows in the pipes. The computed results have been compared with the experimental data of Snyder & Lumley and Wells & Stock for horizontal and vertical pipe flows, and good agreement was observed.
