Mixed Convection Boundary Layer Flow near the Lower Stagnation Point of a Solid Sphere with Newtonian Heating

The steady mixed convection boundary layer flow near the lower stagnation point of a solid sphere, generated by Newtonian heating in which the heat transfer from the surface is proportional to the local surface temperature, is considered in this study, The governing, boundary layer equations are first transformed into a system of non-dimensional equations via the non-dimensional variables, and then into non-similar equations before they are solved numerically using an implicit finite-difference scheme known as the Keller-box method. Numerical Solutions are obtained for the velocity and temperature profiles with two parameters, namely the mixed convection parameter lambda and the Prandtl number Pr.
