Abstract


This paper provide information on Amplification of heat transfer over a surface equipped with Hexagonal drilled pin fins in alternate arrangement in a rectangular path. Fin dimensions are 100 mm in height and 25 mm of each edge. Channel had cross-section area about 250-100mm2. The experiment covered the following range: Reynolds no. 13,500-42,000, (C/H) clearance ratio is about 0, 0.33 and 1, (Sy/D) the inter-fin spacing ratio is about 1.208, 1.524, 1.944 and 3.417. Sy that is stream wise distance varies and Sx that is span wise distant is constant. Friction factor and Nusselt no. are Key parameter which relates with efficiency improvement and heat transfer rate. The friction factor, enhancement efficiency and heat transfer correlated in equation with each other. Alternate arrangement and holes enhance the heat transfer rate. Clearance ratio and inter-fin gap ratio and comparatively lower Reynolds no. give higher thermal attainment.

Keywords


heat transfer enhancement; drilled pin fins; performance analysis; Alternate arrangement.
