摘要
Through experimental investigation, this study offers a closer look into the performance of the vortex tube energy separation under different geometrical parameters; mainly tube length, diameter and internal tapering angle. Also the study evaluates the effect of inlet pressure on the performance of the vortex. The data shows that the tested vortex tube has an optimum length between 66 mm and 158 mm, an optimum diameter between 9 mm and 26 mm and a tapering angle smaller than 4°. Finally the experimental data show that the higher the inlet pressure, the greater the temperature difference however there is a maximum value where performance starts to deteriorate due to inlet nozzle choking.
