ELECTROMAGNETOCONVECTIVE STAGNATION POINT FLOW OF BIONANOFLUID WITH MELTING HEAT TRANSFER AND STEFAN BLOWING

ABSTRACT
This study investigates the effect of induced magnetic field, melting heat transfer and Stefan blowing effects of mass transfer as well as mass convective boundary condition on the stagnation point flow of a bionanofluid over a vertical plate. The non-linear boundary-layer equations are transformed, by using suitable similarity transformations, into ODE which are then solved numerically using the bvp4c technique. The solutions of the problem depends on parameters of magnetic, blowing, Brownian motion, thermophoresis, reciprocal of magnetic Prandtl number, Lewis number, Bioconvection Schmidt number, and Peclet number. The effects of these controlling parameters on the flow, heat, mass and microorganism transfer are studied. It is found that magnetic parameter leads to a decrease in the thickness of the momentum boundary-layer. The temperature profile decreases with the increase of melting parameter. The blowing parameter enhances the concentration. The results of the present study are useful in many industrial applications such as heat exchangers, coolants, micro-channel heat sinks, lubricants, and microbial fuel cell.
