涡流管是一种将压力流体同时分离成冷热流体流的装置。科学界已经做了大量的实验和理论研究，因为发明的涡流管，以增加性能的管通过改变几何和操作参数;本文涉及参数审查所有这些工作。综述了近14个参数对涡流管性能的影响。它包括管的几何形状的发展，如长径比，喷嘴的数量，热端阀的角度和冷孔直径等讨论沿着随着不同的流体和操作参数，如CMF和滞流点等。大多数的理论和实验研究的重点是研究热分离和几何优化的机制。本次审查的主要目标是讨论所做的努力，以提高制冷效果，使缺失的环节，可以帮助未来的研究。
Vortex tube is the device that separates pressurized fluid into hot and cold fluid streams simultaneously. The scientific community has done extensive experimental and theoretical studies since invention of vortex tube to augment the performance of the tube by varying geometrical and operational parameters; the paper deals with parametric review of all such work. The review takes into account effect of almost 14 parameters on performance of vortex tube. It includes developments in tube geometry like L/D ratio, number of nozzles; hot end valve angle and cold orifice diameter etc. are discussed along with different fluids and operational parameters like CMF and stagnation point etc. The focus of most of the theoretical and experimental studies was to investigate mechanism of thermal separation and geometry optimization. The main objective of this review is to discuss efforts made in order to enhance the refrigeration effect so that, missing links could help for future research.
