This study reports the analysis of heat transfer of a flat surface which equipped with cylindrical perforatedpin fins in staggered arrangement in a rectangular duct. Dimensions of the base plate in the rectangular duct 145mm x220mm . Flat surface (Base plate) which is attached with a heater. The range of Reynolds number is fixed & about 2000–12,000, the clearance ratio (C/H) as 0.0, the inter-fin spacing ratio (Sy /D) are 2.4, 3.6 and 4.8. Stream wise distanceSy is kept at constant and span wise distance Sx varies. The friction factor, enhancement efficiency and heat transfercorrelate in this equations with each other. Here we are comparing cylindrical perforated pin fin with different numberof perforations(n) and different dia. of perforation (Dp) of pin fins with each other. Staggered arrangement and optimumperforation modification will enhance the heat transfer rate and they relatively influences on the flow characteristics.Friction factor & Nusselt number are Key parameters which relate with efficiency enhancement and heat transfer rate.
