摘要

本文研究了Ranque-Hilsch涡旋管内的流动，采用了不同封闭程度的湍流模型，从显式代数雷诺应力下的线性涡粘到微分雷诺应力模型。非定常流场特征可以用微分雷诺应力模型来解决。结果与本文第一部分报告的实验数据进行了验证，并显示了定性和定量的一致。详细分析了流动拓扑结构和非定常效应。

THE FLOW FIELD INSIDE A RANQUE-HILSCH VORTEX TUBE PART II: TURBULENCE MODELLING AND NUMERICAL SIMULATION

The flow in a Ranque-Hilsch vortex tube was investigated using turbulence models of different closure levels ranging from linear eddy viscosity over explicit algebraic Reynolds stress to differential Reynolds stress models. Unsteady flow features could be resolved with the differential Reynolds stress model. The results were validated against experimental data reported in part I of this paper and show qualitative as well as quantitative agreement. A detailed analysis of the flow topology as well as unsteady effects is presented.
