The vortex tube is a device, having no moving parts, which generates hot air and cold air simultaneously at its two ends from an inlet of compressed air. In this study, performance of hot cascade type Ranque-Hilsch vortex tube, with a length to diameter ratio (L/D) of 20 with different pressures 8, 9, 10, 11, and 12 bars, on the basis of CFD results were investigated. The total outlet hot kinetic exergy, total outlet hot physical exergy, total outlet cold kinetic exergy, total outlet cold physical exergy and total outlet exergy were investigated by using CFD software data. It was found that high total outlet exergy was obtained at the pressure of inlet air 12 bar.
