Effects of Radiation on Free Convection Non-Darcy Flow along Non-isothermal Vertical Wall Embedded in a Porous Medium with Heat Generation

Abstract

This work presents a numerical study to simulate the effect of thermal radiation on natural convection non-Darcy flow along non-isothermal vertical plate embedded in a porous medium with heat generation. Similarity solution is used to convert the governing differential equations from its dimensional form to its dimensionless form.  Finite difference method is used to convert the dimensionless governing differential equations of the problem to its numerical form, and then it’s programmed by using Fortran language. The work of the program is tested by making a comparison between present work and previously published work, and the result of the comparison is good, after that the program is run to give the results related to this study. Dimensionless velocity and temperature profiles as well as local Nusselt number are presented and discussed in detail for various values of involved parameters. From this result it can infer that the raise in the power law index of variable wall temperature, radiation parameter, and radiation parameter but in presence of heat generation enhances the amount of heat transfer. The increase in the Forchheimer parameter, Rayleigh number, and heat generation parameter lead to lessen the amount of heat transfer.
