Homogeneous-heterogeneous reactions in MHD flow due to an unsteady curved stretching surface

This article addresses, the homogeneous-heterogeneous reactions effects in magnetohydrodynamic (MHD) flow of viscous fluid flow by a curved stretching surface. Fluid is electrically conducting in the presence of an applied magnetic field. System of ordinary differential equations is obtained by appropriate transformations. Convergent series solutions are computed for the resulting nonlinear differential system. Impact of different parameters on the velocity, temperature and concentration profiles is examined. Computations for pressure, surface drag force and heat transfer rate are presented and examined for the influences of pertinent parameters. It is noted that fluid velocity enhances when curvature parameter is increased. Surface heat transfer rate enhances for larger Prandtl number. Further, the concentration distribution decreases for larger values of strength of homogeneous reaction parameter while it increases for strength of heterogeneous reaction parameter.
