Radiation Effect on MHD Mixed Convection Flow Along an Isothermal Vertical Wedge Embedded in a Porous Medium with Heat Generation

Abstract

This paper study the effect of radiation on a steady mixed convection flow of aviscous incompressible electrically conducting and radiating fluid over an isothermalvertical wedge embedded in a porous medium. The governing nonlinear partialdifferential equations and their boundary conditions are transformed into a nonsimilarform by using a suitable dimensionless variables. The system of nonsimilar equations issolved numerically using a finite difference method. The present results of local Nusseltnumber are compared with previously published work for the case of Darcy solution.The comparison is found to be in excellent agreement. The present results showed thatas the wedge angle parameter increases the local Nusselt number increases. Increasingin the value of the square of the Hartmann number leads to decreasing the value of thelocal Nusselt number. Increasing in the value of the radiation parameter leads to anincrease in the value of the local Nusselt number. Increasing in the value of the heatgeneration parameter leads to decreasing the value of the local Nusselt number.Increasing in the value of the radiation parameter in the presence of the square of theHartmann number and the heat generation parameter has a similar effect on the localNusselt number presented above but with less values.
