When a compressed air is supplied tangentially to a vortex tube, the total temperature separation is generated between the cold and hot air outlets by the swirling flow field formed inside the cylinder. By using the vortex tube, the industrial local coolers have been applied with the cold air of this device, such as called Ranque-Hilsch tube. Although this system has various advantages in terms of ease of maintenance and environmental protection, its practical application is limited due to the difficulty of temperature control. In this study, for the sake of the improvement of this device, we mainly focus on whistling and intermolecular heat transfer, so we engaged a CFD to investigate this total temperature separation mechanism. The characteristics of the temperature distribution and its change inside the device have been discussed.
