A comprehensive numerical study is conducted to investigate effect of nonlinear thermal radiation on MHD boundary layer flow and melting heat transfer of micro polar fluid over a stretching surface with fluid particles suspension. Using suitable transformations, the governing equations of the problem are transformed in to a set of coupled nonlinear ordinary differential equations and then they are solved numerically using the Runge–Kutta–Fehlberg-45 method with the help of shooting technique. Authentication of the current method is proved by having compared with established results with limiting solution. The impact of the various stimulating parameters on the flow and heat transfer is analyzed and deliberated through plotted graphs in detail. We found that the velocity, angular velocity and temperature fields increase with an increase in the melting process of the stretching sheet. Also it is visualize that the shear stress factor is lower for micro polar fluids as compared to Newtonian fluids, which may be beneficial in flow and heat control of polymeric processing.

AbstractThe main purpose of this work is to investigate unsteady magnetohydrodynamic (MHD) boundary layer flow of Maxwell fluid over a stretching surface with nonlinear thermal radiation. Heat and mass transfer analysis is carried out in the presence of convective boundary conditions and first-order chemical reaction. A uniform magnetic field is applied normal to the direction of the fluid flow. The nonlinear coupled partial differential equations are solved numerically using an implicit finite difference method with quasi-linearization technique. Effects of the emerging parameters on the dimensionless velocity, temperature and concentration are investigated. The rate of heat transfer in terms of Nusselt number and rate of mass transfer in terms of Sherwood number are also computed and addressed.
