Mhd Natural Convection Flow along a Vertical Wavy Surface in Presence of Heat Generation/absorption with Viscosity Dependent on Temperature

The present numerical simulation is analyzed the Magnetohydrodynamic natural convection flow and heat transfer along a uniformly heated vertical wavy surface in presence of heat generation/absorption with temperature dependent variable viscosity. Using the appropriate transformations the governing boundary layer equations are reduced to non-dimensional forms. The resulting nonlinear system of partial differential equations are mapped into the domain of a vertical flat plate and then solved numerically applying implicit finite difference method together with Keller-box scheme. The solutions are expressed in terms of the skin friction coefficient, the rate of heat transfer, the streamlines as well as the isotherms over the whole boundary layer. The implications of heat generation/absorption parameter (Q) and viscosity parameter (ε) on the flow structure and heat transfer characteristics are investigated in detail while, Prandtl number (Pr), magnetic parameter (M) and the amplitude-to-length ratio of the wavy surface (α) are considered fixed. Comparison with previously published work is performed and is found to be in good agreement.
