Experimental investigation of energy-exergy analsis of ranque-hilsch vortex tube with condensed parallel connection

In this study, two counterflow Ranque-Hilsch Vortex Tube (RHVT) with internal diameter of 7 mm and body length of 100 mm, with no moving parts except a control valve, were used to adjust the volumetric gauge. Two opposing RHVTs were connected in parallel to form an experimental system. In the developed experimental system, pressurized air with 50 kPa pressure range from 150 kPa to 550 kPa was used as the fluid in RHVT. Nozzles 2, 4 and 6 manufactured from Polyamide, Aluminum and Brass materials were used in RHVT. In the experiments, the control valve on the hot fluid outlet side of the RHVT is left in the fully open position. The energy dissociation phenomenon in the RHVT system with counterflow parallel connection was experimentally investigated, exergy analysis was made and suggestions were made to improve performance.
