MHD FLOW AND NONLINEAR RADIATIVE HEAT TRANSFER OF A CASSON NANOFLUID PAST A NONLINEARLY STRETCHING SHEET IN THE PRESENCE OF CHEMICAL REACTION

摘要

In this study, we analyzed the nonlinear thermal radiation effect on boundary layer flow and heat transfer of Casson nanofluid past a nonlinearly stretching sheet in the presence of chemical reaction. The nonlinear partial differential equations are transformed into a set of nonlinear ordinary differential equations using self-suitable transformations, which are then solved numerically using the fourth-fifth-order Runge–Kutta–Fehlberg method with the help of symbolic algebraic software MAPLE. The effects of different nondimensional parameters on velocity and temperature profiles along with the friction factor and local Nusselt number are discussed through graphs and tables. The results indicate that the Casson parameter have a tendency to control the flow, and nonlinear thermal radiation enhances the thermal boundary layer thickness.
