RESUMO

An analysis is accomplished to investigate the features of heat transfer and fluid flow of a steady laminar magnetohydrodynamics (MHD) mixed convection flow of water around a rotating sphere. The transformed governing equations of the non-similar boundary layers are solved by an implicit finite difference method along with the quasi-linearization technique. It is perceived that both the local friction coefficients in the x and y directions and the heat transfer coefficient are increasing and the point of separation is delayed with increasing magnetic parameter, suction parameter, and buoyancy force.
