“…It is also used in the separation of air into nitrogen and oxygen rich fluid stream [14,15] which makes the VT a possible candidate for the use in the in-flight ACES (air collection and enrichment system) of air breathing propulsion. The VT has many advantages [16e19] because of its low cost, light weight, reliability, compactness and free maintenance as it has no moving parts.…”

In this article, the development of the energy separation for the vortex tube has been briefly reviewed. This review mainly focuses on three aspects, they are the energy separation principle, the design criteria of vortex tubes, and practical application. First, the research progress on the energy separation principle of the vortex tube from several aspects has been introduced, such as friction, pressure gradient, acoustic streaming, secondary circulation and multi-circulation theory. In addition, the control factors that affecting the performance of the vortex tube were summarized. Furthermore, due to its simple structure, safety and stability, the vortex tube is widely used in the field of refrigerating and heating, mixture separation. This survey, while extensive cannot cover all papers, some selection is necessary. The purpose of this review aims to summarize the important works of literature on the energy separation of vortex tube as well as identify limitations to existing studies and directions for future research.

The Ranque-Hilsch vortex tube is a simple device with no moving parts and no mechanical operations. This tube separates the inlet air into two distinctive regions; an outward high temperature region and an inner low-temperature one. A computational study of the vortex tube is presented in this article using the ANSYS Fluent ® software whose results showed good agreement with the experimental measurements. The effects of different geometrical parameters such as the tube length to diameter ratio and the cold orifice size on the coefficient of performance of the tube were investigated. The results showed that the coefficient of performance (COP) of the tube is highly affected by the tube length to diameter ratio (L D), and this effect varies when operating at different cold mass fractions where the maximum coefficient of performance occur at cold mass fraction of 0.64. The results also showed that the coefficient of performance of the tube is also affected by the cold orifice to tube diameter ratio (c d D) and that the maximum (COP) at any (c d D) ratio occurs also at a cold mass fraction of 0.64.
