Résumé

This study examines the performance analysis of two counter flow Ranquee–Hilsch Vortex Tubes (RHVT) having the same geometrical properties in the condition of serial and parallel connection. The performance of CO2 as a working fluid in the vortex tube by using nozzles having 2,4 and 6 orifices, which were manufactured from polyamide and brass material has been experimentally investigated. Experimental studies were carried out by compressing CO2 through the compressor to the vortex tube at pressures between 150 and 550 kPa. The most important physical property of a RHVT is the ratio of L/D which is equal to 14 in this study. In addition, by using the data obtained from experimental results, the second law efficiency was calculated for different working conditions of the systems by exergy analysis. The highest overall temperature difference ( _T ) was obtained as 76.9 K when using parallel connected RHVT system with brass-six nozzle.
