Natural Convection Flow Along a Vertical Wavy Surface with the Effect of Viscous Dissipation and Magnetic Field in Presence of Joule Heating

The combined effect of viscous dissipation and Joule heating on magneto-hydrodynamic (MHD) natural convection flow along a uniformly heated vertical wavy surface has been investigated in this paper. Using a set of appropriate transformation the governing boundary layer equations are converted into dimensionless non-similar equations and solved numerically by the finite difference method, known as Keller-Box scheme. Numerical solutions are obtained for velocity, temperature, local skin friction and Nusselt number which are shown graphically in figures along for the wavy surface for a selection of parameter sets consisting of Joule heating parameter, Eckert number, Pradtl number and MHD parameter. Numerical results show that these parameters have significant influences on the velocity and temperature as well as for the local friction and Nusselt number.
