Investigate the Effect of length parameter on heat transfer rate in porous fin in natural convection

Always considering the scientific community as well as various industries including electronics industries to find new techniques to increase the heat transfer rate. The use of a porous media due to increase the effective surface provides a new window in this context. Therefore, in this study we are trying to find the optimal length for porous fin. In this study the effect of heat convection considered on a rectangular fin. Porous fin allows fluid to flow through and cause a better Natural Convection and Heat Transfer between them. Darcy Models have been applied to formulate Heat Transfer which is presented as a second order nonlinear equation. Geometry and porosity are classified with a Dimensionless Parameter. Thermal behaviors of Fins on Temperature Reduction including: long fin, finite-length fin with insulated tip, finite-length fin with known Convective Coefficient at the tip and finite-length fin with known temperature at the tip are found. Amount of Temperature Reduction and heat transfer are calculated.
