Abstract
Extended surfaces are widely used in various applications like aerospace parts design, cooling and also in solar collectors for effective dissipation of heat. The present paper gives us an idea about the heat transfer analysis for solid pin fin and perforated pin fins that are fitted in a rectangular chamber. The rectangular chamber has a cross section area of 300 * 200 mm2. It is concluded from the experiment that perforated pin fin always works better as compared to solid pin fin in all conditions. Moreover, for lower range of Reynolds number, solid pin fin performs better whereas for higher range of Reynolds number, perforated pin fin performs better as compared to circular pin fin.
