The flow and heat transfer nature of MHD dissipative flow past the upper part of a non-melting paraboloid of revolution with non-uniform heat source/sink, thermophoresis and Brownian moment effects are investigated numerically. The buoyancy induced on the flow is considered in such way that the surface is neither vertical/horizontal nor wedge/cone. The equations governing the flow are solved numerically by employing the RKF integration scheme after suitable transformations. Graphical results are obtained to discuss the behaviour of flow, temperature and concentration fields at various parameters of interest. The reduced wall friction, local Nusselt and Sherwood numbers are computed. It is found that the non-uniform heat source/sink parameters regulate the thermal boundary layer. Thermophoresis and Brownian moment parameters act as controlling parameters of heat and mass transfer rate.
