Thermal Analysis Of Fin Arrays With And Without Perforations For Different Velocities

Abstract

In this paper experimental study on rectangular fin array and its thermal analysis with different perforations using forced convection heat transfer for non-perforated fin and perforated fin was investigated for 4-rectangular fins for 05 different velocities of 6.2 m/sec, 8.7 m/sec, 10.3 m/sec, 12.6 m/sec & 15.4 m/sec. The pattern of perforated rectangular fin contains 2-circular hole of diameter 5mm & 7mm. Results show that the heat transfer coefficient of perforated fin is more in comparison with fin without perforation, it increased with increased in perforation diameter. Also, it is found that heat dissipation enhancement, higher efficiency and effectiveness for fin with perforation, with increasing the diameter of perforation in addition to the considerable reduction in weight in comparison with fin without perforation.
