A Study and Fabrication of Vortex Tube

Refrigeration plays vital role in developing countries primarily for the preservation of food, medicine and for air conditioning. Conventional refrigeration systems are using Freon as a refrigerant. As they are the main cause for depletion of ozone layer, extensive research work is going on alternate refrigeration systems. Vortex tube is a non-conventional cooling device, having no moving parts which will produce cold air and hot air from the source of compressed air without affecting the environment. An experimental investigation is to be performed in order to realize the behavior of a vortex tube system. In this work attention has to be focused on the classification of parameters affecting vortex tube operation. The effective parameters are divided into two different types, namely geometrical and thermo-physical ones. The reliable test rig is to be designed and constructed to investigate the effect of geometrical parameters like diameter and length of main tube, diameter of outlet orifice, and shape of entrance nozzle. The thermo physical parameters are inlet gas pressure, types of gas, cold gas mass ratio and moisture of inlet gas.
