Numerical Study of Heat Transfer through Fin by using ANSYS-Fluent Model

Abstract

A mathematical model of the process occurring on fin at same height and different height with different heat flux (10000, 20000, 30000 w/m2) have been investigated. The model is developed using principles of heat transfer, fluid dynamics, and these values used for comparing with two height of fin which used in electronically device like computer. The distributions of velocity and temperature was found along flow path of fin cell using the software computer (ANSYS FLUENT 16.1), this software was developed to apply the theoretical model to simple three -dimensional geometry. Finally the optimal heat flux and temperature along fin has been obtained for five tests of fins, and a good agreement is found between theoretical results with previous works.
