The Ranque-Hilsch vortex tube is a device for continuously separating an inlet pressurized fluid stream into two outlet streams of warmer and cooler temperatures at lower pressures, with no moving parts and without any heat or work effects. It has been applied to cool or heat small systems where refrigeration is impractical. Studies of the fluid mechanics inside the tube have not fully established the flow structure that provides the separation. Thermodynamic energy and entropy balances giving relations among properties and the relative amounts of the three fluid streams have been examined to determine consistency among measured data along with sensitivity of the phenomena to tube configuration, measurement error, and properties. The strong response of the temperature separation to small variations in entropy generation is shown to limit the possibilities for generalized prediction of vortex tube behavior. © 2017 American Institute of Chemical Engineers AIChE J, 2017

用于Ranque-Hilsch涡流管分析和设计的详细热力学

Ranque-Hilsch涡流管是一种用于将入口加压流体流在较低压力下连续分离为两个温度较高和较低的出口流的装置，该装置没有活动部件，也没有任何热或功效应。它已被应用于无法进行制冷的小型系统的冷却或加热。对管内流体力学的研究尚未完全建立提供分离的流动结构。已经检查了热力学能量和熵平衡，这些热力学能量和熵平衡给出了特性与三种流体流的相对量之间的关系，以确定测量数据之间的一致性以及现象对管道配置，测量误差和特性的敏感性。温度分离对熵产生中的小变化的强烈响应显示出限制了对涡流管行为的一般性预测的可能性。©2017美国化学工程师学会AIChE的Ĵ，2017年
