Experimental Comparison of Natural Convection Heat Transfer from Blackened Horizontal Fins and Blackened V-Fins on a Vertical Plate

Abstract

Convection is usually the dominant form of heat transfer in liquids and gases. Although sometimes discussed as a third method of heat transfer, convection is usually used to describe the combined effects of heat conduction within the fluid (diffusion) and heat transference by bulk fluid flow streaming. Convective heat transfer is the transfer of heat from one place to another by the movement of fluids, a process that is essentially the transfer of heat via mass transfer. Bulk motion of fluid enhances heat transfer in many physical situations, such as between a solid surface and the fluid. This paper refers to the convective heat transfer from a V-Fin Array whose surface is made black and the fins are sticked to it to form horizontal fin array and in form of V-Fins to form V-Fin array.
