Abstract:
In this study, 3 different vortex generators (generators) called inclined, flower and s-type were designed and 9 vortex generators were produced, each design having 4, 5 and 6 nozzles. In the experimental study, three different fluids were used: argon, carbon dioxide and mixture gases. These fluids were applied to the system as 200, 250 and 300 kPa. The experiments were carried out according to the Taguchi L9 experimental designs, which were organized separately for each nozzle type. According to the different operating parameters determined in the vortex tube, the temperature difference, performance efficiency coefficient (COP) and exergy efficiency were calculated. According to the Taguchi-based grey relational analysis method, the optimum operating parameters were determined for temperature difference, performance efficiency coefficient (COP) and exergy efficiency. This study has made an important contribution to the determination of the effects of vortex generators of different designs and different fluids on vortex tube working performance.
