SIMULATION OF THERMAL SEPARATION IN A HIGH VELOCITY VORTEX-TYPE FLOW
Ranque-Hilsch vortex tube (or vortex tube) is a device for producing the hot and cold air when the compressed air flows tangentially into the vortex chamber through the inlet nozzles. The application of a mathematical model for the simulation of a strongly swirling flow in a vortex tube is presented. A staggered finite volume approach with the standard k-ε model and an algebraic Reynolds stress model (ASM) for 2D compressible, axisymmetrical flows was used to carry out all the computations. Due to the simple geometry and availability of experimental data, a uni-flow vortex tube was simulated to study its velocity field and temperature/energy separation. It is found that a temperature separation in the tube exists and predictions of the temperature fields agree well with measurements. To understand the effects of these tube parameters clearly, a numerical computation was carried out to examine the influence of inlet nozzle locations on temperature separation.
