볼텍스 튜브의 에너지 분리 현상에 관한 수치해석 연구

다국어 초록 (Multilingual Abstract)

In order to find the operational principle of the vortex tube, CFD analysis of the flow field in the vortex tube has been carried out and the results have been scrutinized to pursue the energy separation mechanisms in details. It was found that the energy separation mechanism in the vortex tube consists of basically two major thermodynamic-fluid mechanical processes. One is the isentropic expansion process at the inlet nozzle, during which the gas temperature is nearly isentropically cooled. Second process is the viscous dissipation heating due to the high level of turbulence in both flow passages toward cold gas exit as well as the hot gas exit of the vortex tube. Since the amount of such a viscous heating is different between the two passages, the gas temperature at the cold exit is much lower than that in the gas at hot exit.
