Modeling the thermo physical behavior of metallic porous fin on varying convective loads

Abstract

Background/ Objectives: Porous-permeable structured fins are the principal operational mechanism for enhancing the percentage of heat evolved and dissipated because of their many thermo physical characteristics. Study of thermal gradients on the basis of convective loads in porous fins is important in many engineering fields. Methods: In the present fractional investigation, well-established optimal homotopy asymptotic method (OHAM) has been applied on thermal system expressed in nonlinear fractional order of ordinary differential equations for Darcy's approach for porous-structured fin. Here parameters related to porosity, permeability and convection have been deliberated. In order to study the thermal solicitations, the thermal analysis with insulated tip of copper based alloy is studied. Findings: It is found that porosity of system is influencing more than other factors. Novelty: This study demonstrates the efficiency of OHAM as well.
