چکیده مقاله:
Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimental results are used for validating the numerical model. The numerical analysis of perforated pin fin with varying parameters such as diameter of perforation, location of perforation and number of perforations is done. The perforated pin fin is found to enhance heat transfer rate compared to ordinary pin fin with a lesser material requirement
