Effect of L/D Ratio on Thermal Performance of Ranque-Hilsch Vortex Tube: Experimental study on the influence of L/D ratio on the thermal performance of Ranque-Hilsch vortex tube

Abstract

Vortex tube separates pressurized fluid into hot and cold fluid streams simultaneously. Geometrical and operational parameters affect this separation. The study deals with experimental investigations of effect of L/D ratio (15, 16, 17 and 18). For all the experiments, air is working fluid. Air is supplied at different pressures ranging from (200 to 600 kPa in steps of 100kPa). CMF variation is in the range from 0 to 1 for all geometries. The effects on energy separation are analyzed with respect to CMF and Mach number. The results are expressed in percentage rise and drop. Similarly relation is developed and results are compared with literature.
