Review Paper on Experimental Investigation on Vortex Tube Refrigeration System

A vortex tube is a simple device which splits a high pressure gas stream into a cold and hot stream without any chemical reactions or external energy supply. It is a mechanical device without any moving parts. The splitting of flow into regions of low and high temperature range is referred to as the temperature separation effect. The performance of vortex tube depends on two basic parameters, first is the working parameter such as inlet pressure of compressed air, and the other one is geometric parameters such as number of nozzles, diameter of nozzle, cone valve angle, length of hot side tube, cold orifice diameter, and as well as material of vortex tube. Vortex tube has interesting functions and several industrial applications, and, as a refrigerator, it is used as a spot cooling device in industry.
