Comparative Numerical Analysis of Heat Transfer between Nonporous and Porous Cylindrical Fins

Abstract

Fin is the easiest and cheapest way in enhancing heat transfer of all other methods like increasing fluid velocity, ionizing fluids, using additives, causing vibration etc. It has a lot of applications in the growing number of engineering disciplines. The main purpose of this paper is to enhance heat transfer of cylindrical fin by perforated and axial holes which increases surface area but decreases material cost. Finding out the proper length of the fin is another goal of this paper which also reduces fin size and material cost. Steady state thermal simulation has been done using ANSYS 17. An attempt is made to find out temperature distribution by varying geometry, materials. Investigations show that porous cylindrical fin drops maximum temperature and hence maximum heat transfer occurs because of the increasing ratio of perimeter to cross-sectional area. Porous cylindrical fin also has light mass with low cost. And the proper length of cylindrical fin increases with the increase in diameter.
