A vortex tube is a simple energy separating device which splits a compressed air stream into a cold and hot stream without any no moving parts, external energy supply or chemical reactions. This paper focuses on the effect of the size of hot nozzle on the performance of the Ranque–Hilsch vortex tube. The present research has focused on the energy separation and flow field behavior of a vortex tube by utilizing both straight and helical nozzles. Basically three kinds of nozzles set include, 3 and 6 straight types and 3 helical type’s nozzles have been investigated and their principal effect on cold temperature difference was compared. All vortex tubes dimensions are kept the same for models. All these performances analysis is done on three dimensional flow domain using Computational Fluid Dynamics (CFD).
