Heat transfer and fluid flow characteristics of perforated pin-fin arrays


R Muthukumaran, R Rathnasamy, R Karthikeyan

This work presents the outcomes of experimental investigation on heat transfer and friction characteristics over a rectangular-horizontal base plate maintained at 50°C with cylindrical and perforated pin–fin heat sinks with inline arrangements were designed and tested. The effect of distance between fins in the span-wise and stream-wise directions has been determined. The values of the relative stream wise pitch (Sy/d = 1.2, 2.4, 3.6) and the relative span wise pitch at (Sx/d =1.2). The experiments covered following ranges: Reynolds number ranges from 2000-25000, the clearance ratio (C/H= 0.0). Nusselt number and friction factor were considered are performance parameters. The results of the perforated fin compared to cylindrical fin can produce higher heat transfer rate. The present results were found to be optimal inter-fin pitches Sx /d=1.2 and Sy /d=1.2.
