Vortex tube is a mechanical device that separates compressed gas into hot and cold streams. When high pressure air enters into the vortex chamber through one or more tangential nozzles, a strong vortex flow created which splits into two regions. The high temperature air near the boundary of the tube leaves circumferentially through the conical valve where as the air at lower temperature leaves through the cold orifice. A conical valve is adjusted with the hand control knob allows for adjusting the volume and temperature of air coming out from the cold end. There is no maintenance, no mess, no explosion hazard, no electricity, and no moving parts in using the vortex tube. Vortex tubes behave in a very predictable and controllable way. The only disadvantage with the vortex tube is its low coefficient of performance (COP).The Vortex tube used for experimental work is manufactured using composite material Poly Tetra Fluoro Ethylene (PTFE TEFLON RODS). An Experimental work has been carried out to analyze the performance of vortex tube that influences the effect of five controllable input variables namely diameter of the orifices, diameter of the nozzles, length of hot tube, tube diameter and inlet pressure over the temperature difference in the cold side as output using Taguchi Method. Experiments were conducted at different input pressures of air, viz., at 2, 4 and 6 bars and for different diameters of orifices, viz., 5 mm ,6.5 mm and 8 mm. The source for compressed air input to the vortex tube was reciprocating air compressor. The various Parameters like main effect analysis, analysis of variance (ANOVA) and Optimal Cold Temperature were carried out in order to determine the effects of process parameters and optimal factor settings. Finally, the confirmation test is carried out to verify the accuracy of Taguchi method.
