| 摘 要： | 本文建立了基于一种合理考虑湍流-离心力相互作用的新的代数Peynolds应力模型和颗粒随机轨道模型的强旋湍流气固两相流动数学模型。应用该模型对新型涡旋管内的强度湍流气固两相流进行了数值模拟，揭示了涡旋管内气固两相湍流流动的基本特性以及改变切向出口气体流率对流动的影响。

| Abstract: | A mathematical model for strongly swirling gas particle turbulent flow is formulated in this paper, based on a new algebraic Reynolds stress model accounting properly for turbulence swirl interactions and the particle stochastic trajectory model. The present model is utilized to simulate numerically the strongly swirling gas particle turbulent flows in a novel vortex tube. The calculated results show the features of the gas particle turbulent flow and delineate the effect of gas flow rate through the tangential exit on the flow field in the vortex tube. |
