Abstract	The vortex tube (also called the Ranque–Hilsch vortex tube) is a mechanical device operating as a refrigerating machine without any moving parts, by separating a compressed gas stream into two low pressure stream, the temperature of which are respectively higher and lower than inlet stream. Such a separation of the flow into regions of low and high total temperature is referred to as the temperature (or energy) separation effect. The vortex tube performance depends on two types of parameters, firstly air or working parameters such as inlet pressure of compressed air, cold mass fraction and secondly tube or geometric parameters such as length of hot side tube, cold orifice diameter, number of nozzles, diameter of nozzle, cone valve angle and also material of vortex tube affects Coefficient of Performance (COP). This paper discusses the experimental investigation of effect of above working parameters on the performance of Ranque-Hilsch vortex tube. The brass material has been used for manufacturing of the vortex tube as it has better thermal conductivity and less fluid friction losses. In this experimental study the performance of vortex tube has been tested with compressed air at various pressures from 2-8 bar, which supplied through single tangential inlet nozzles. The L/D ratio of hot side tube varies 12.5 , 13.5 and 17.5 and cold mass fraction varied from 0 – 1.
