Effects of Electromagnetic Field on the Thermal Performance of Longitudinal Porous Fins with Temperature-dependent Internal Heat Generation

Abstract

Excessive heat generation in systems often leads to their thermally-induced failures, continuous technical progress is important for high-performance equipment. Therefore, there is a need for an effective cooling of the such thermal equipment. In this present work, the thermal behavior of a convective rectangular porous fin exposed to an electric and magnetic field and with temperature-dependent internal heat generation was studied using differential transformation method. A good agreement was established between the results of the differential transformation method and the numerical method's results. Consequently, the significance of electromagnetic, porosity, convective, internal heat generation on the thermal performance of the porous fin are investigated using the approximate analytical method. The exploration of the impacts of the parameters on the passive device reveals that increasing the electromagnetic field, porosity and convective heat transfer parameters cause increase in the rate of heat transfer from the base of the fin. However, an increase in the internal heat generation and the thermal conductivity parameters cause the fin temperature to increase. It is believed that the present work will help in the better design of the passive device especially in an electromagnetic environment.
