计算流体动力学（CFD）和实验研究进行了优化的Ranque-Hilsch涡流管。通过CFD分析对不同类型的喷嘴轮廓和喷嘴数量进行了评估。对旋流速度、轴向速度和径向速度分量以及包括二次环流在内的流态进行了分析。通过CFD分析得到了最佳冷端直径（d（c））和长径比（L/D）以及获得最高热气体温度和最低冷气体温度的最佳参数，并通过实验进行了验证。计算了涡流管作为热机和制冷机的性能系数。(c)2005爱思唯尔有限公司保留所有权利。
Computational fluid dynamics (CFD) and experimental studies are conducted towards the optimization of the Ranque-Hilsch vortex tubes. Different types of nozzle profiles and number of nozzles are evaluated by CFD analysis. The swirl velocity, axial velocity and radial velocity components as well as the flow patterns including secondary circulation flow have been evaluated. The optimum cold end diameter (d(c)) and the length to diameter (L/D) ratios and optimum parameters for obtaining the maximum hot gas temperature and minimum cold gas temperature are obtained through CFD analysis and validated through experiments. The coefficient of performance (COP) of the vortex tube as a heat engine and as a refrigerator has been calculated. (c) 2005 Elsevier Ltd. All rights reserved.
