A Literature Review on Natural Convection Heat Transfer Mechanism using Fins

Abstract

Heat transfer under the natural convection occurs due to the temperature difference between the solid surfaces and the surrounding cold atmosphere. The buoyancy motion enables the fluid movement, initiating the heat transfer between the Heat Sink and the Surroundings. This heat transfer mechanism shall be enhanced further by the optimal location, orientation and placement of fins in such a way that the flow turbulence was introduced. This review journal provides a comprehensive summary of the recent research work on fins for improving the heat transfer rate. Also, the numerical simulation (CFD) methods, experimental studies on natural convection, various fin shapes and their influences on natural convection heat transfer rate.
