Optimization of UPVC material vortex tube for manufacturing cost reduction and thermal efficiency improvement

Vortex tube is the device that separates the flow of compressed air into two streams. Separated streams have temperature difference with respect of inlet compressed air temperature. The compressed air enters in the vortex tube, tangential to internal diameter and gets whirling motion. It travels from one end of the tube to other end and is partially reflected back by the valve. The free and forced vortex, gives rise to hot stream and cold stream coming out of either end of the tube. The phenomenon of the heat transfer between two streams is complex because of variation of pressure inside the tube, three dimensional velocity vectors, formation of turbulent eddies etc. the change in the physical parameter also varies the performance of the tube to great extent.
