Computational Investigation of Heat Transfer Analysis through Perforated Pin Fins of Different Materials

摘要

The present work investigates the enhancement of heat transfer rate through staggered perforated pin fins of different materials with increasing number and size of perforations. Three dimensional CFD simulations have been carried out to analyze the effects of fin number, size and materials of fin to enhance heat transfer rate against pressure loss. Results show that the heat transfer rates of perforated fins up to certain perforation number and size are always greater than the solid ones and with the change of fin material heat transfer rate also improves significantly. On the other hand pressure drop through heat sink decreases not only with increasing perforation number but also with size of perforations.
