Slip Hydromagnetic Radiating Flow In Wavy Isothermal Channel With Porous Medium Considering Joule And Frictional Heating

The problem of hydromagnetic mixed convection heat transfer across a porous medium due to buoyancy force, difference in temperature , the presence of pressure gradient and radiation is considered between two finitely long vertical isothermal walls, one of which is wavy. The presence of the heat source and combined effects of viscous dissipation and Joule heating in slip flow regime is taken into account. The resulting nonlinear dimensionless governing equations are linearized by perturbation technique and then solved numerically using the software MAPLE. As a result, the dimensionless velocity, temperature, skin friction coefficient and the Nusselt number are illustrated through the graphs and discussed for different physical parameters.
