Vortex tube shows excellent energy separation effect and is currently being used as a cooler in the industrial field. In addition, if the vortex tube uses an internal flow, a centrifugal effect similar to that of a cyclone dust collector can be obtained. However, studies on the separation of solid particles utilizing the internal flow characteristics of the vortex tube are insufficient. In this study, to utilize a vortex tube for fine particle separation, numerical simulations were used to compare and analyze the fine particle separation efficiency according to the uni-flow type cold flow ratio. As a result of the simulation, all particles were discharged to the high temperature outlet end along Hie tangent of the tube wall without the effect of cold flow fraction and particle size.
