Experimental Analysis Of Heat Transfer From Square Perforated Fins In Staggered Arrangement

This project gives the experimental analysis of heat transfer over a flat surface equipped with Square perforated\ud pin fins in staggered arrangement in a rectangular channel. The Fin dimensions are 100mm in height & 25mm in\ud width. The range of Reynolds number is fixed & about 13,500– 42,000, the clearance ratio (C/H) 0, 0.33 and 1,\ud the inter-fin spacing ratio (Sy /D) 1.208, 1.524, 1.944 and 3.417. Sy i.e. stream wise distance is varies and Sx i.e.\ud span wise distance is constant. The friction factor, enhancement efficiency and heat transfer correlate in\ud equations with each other. Here we are comparing Square pin fins with cylindrical pin fins. Staggered\ud arrangement and perforation will enhance the heat transfer rate. Clearance ratio and inter-fin spacing ratio affect\ud on Enhancement efficiency. Both lower clearance ratio and lower inter-fin spacing ratio and comparatively lower\ud Reynolds number give higher thermal performance. Friction factor & Nusselt number are Key parameter which\ud relates with efficiency enhancement and heat transfer rate
