Abstract— The forced convective heat transfer between perforated pin fin and solid pin fin in cylindrical channel is numerically studied in this paper. Air is employed as the cold fluid and the effect of different number of perforation and hence the heat transfer is studied in detail. In the present work heat transfer is compared between solid and perforated pin fin in cylindrical column. The cylindrical column has diameter of 150 mm and length of 1200 mm. The result shows that the perforated pin fins have higher heat transfer as compared to solid pin fins. Results also show that there is significant increase in convective heat transfer with increase in number of perforation when comparison between single, two, and three holes perforation is done.
