The Ranque Hilsch Vortex tube is a simple device which can be used to separate hot and cold stream from single injection. It can be used in application such as cooling, heating or mixture separation. As compressed air is injected in to the vortex tube with the help of nozzle which are tangentially attached to the vortex tube, high velocity vortex are formed in the tube. Due to the heat transfer in the vortex tube the cold stream is formed at the center part of tube and hot stream is formed at the periphery of the tube. The behavior of flow inside the tube is of very complex nature. To explain the behavior of flow inside the vortex tube several experimental and numerical investigations have been carried out. This paper discusses the effect on the performance of the vortex tube by varying its number of inlet.
