Keller-Box Scheme to Mixed Convection Flow Over a Solid Sphere with the Effect of MHD

Mixed convection is the combination of a free caused by buoyancy forces due to different density and forced external that increase heat exchange rate. This means that, in convection, effect significant besides forces. In this study fluid type with viscoelastic non-Newtonian. The fluids pass over surface sphere form thin layer, which their dominant viscosity called border layer. obtained limiting layer analyzed thickness boundary layer- near lower stagnating point, then dimensional equations, continuity, momentum, energy equations. These equations are transformed into non-dimensional using variables. Further, ordinary differential stream function, so non-similar solved numerically finite difference method Keller-Box. discretization results non-linear it should be linearized newton linearization technique. numerical solutions Prandtl number, viscoelastic, mixed MHD parameters towards velocity profile, temperature wall temperature.
