NUMERICAL ANALYSIS OF APPLICATION OF VORTEX GENERATOR IN PERFORATED PLATE-FIN HEAT SINK

Abstract

Numerousinvestigations had been attempted to enhance the heat transfer rate from the fins. Heat transfer augmentation techniques, Perforations and arrangements of fins are some of the efficient ways to enhance heat transfer. In this study, passive heat transfer augmentation combined with the perforations on fin and numerical simulations were performed for this combined system for different flow conditions characterized by Reynolds Number ranging from 5000 to 40000. The numerical outcomes were validated against the existing experimental data for the solid fin without any perforation. Further, fins with square and circular perforations were investigated for the same flow conditions. Based on the results comparison, in terms of thermal resistance, the circular perforations on the fins provide better heat transfer rate.
