“…In a counter-flow vortex tube, CMF is close to one. 81 Many of the researchers 27,54,79,[82][83][84][85][86][87][88] who have shown experimental occurrences identified the similar effect and named it back flow, reversed flow, and so on. Numerical solutions provided 42,49,51,71,[89][90][91][92][93][94] agree with the presence of secondary circulation.…”

A vortex tube is a device that separates entering compressed fluid into hot and cold fluid streams simultaneously. This energy separation phenomenon inside the tube is a mystery and the mechanism that causes heat transfer needs attention. Since the invention of the vortex tube, the scientific community has taken efforts to search for energy separation mechanisms. Performance augmentation and the physics of energy separation was the objective of many experimental studies. The performance of the vortex tube varies with changes in geometric and operational parameters. Most of the theoretical studies addressed the issue of energy separation. Prospects and issues of energy separation in a vortex tube in view of the literature is the core of this paper. The main objective is to discuss efforts made in order to justify the physics and to identify new areas for research.

“…With the increase of Reynolds number, the maximum thermal enhancement factor is 1.44. Mohd Hazwan et al [10] studied the heat transfer characteristics of the bottom plate around obstacles installed on different surfaces. The results showed that the effect of flow velocity on the heat transfer topology was ignored, whereas the geometry of obstacles had a considerable influence on the level and distribution of heat transfer enhancement.…”
