Abstract
This study examines the flow performance of a chemically reacting magnetohydrodynamics flow of Casson and Williamson fluids on an enlarging surface. It also inspects the significance of thermal radiation, velocity, and thermal slips. The basic equations of the study are reduced into a system of nonlinear ordinary differential equations by applying suitable nondimensional quantities. The renovated equations are cracked by adapting the shooting method. The incitement of physical parameters on the current examination is investigated and discussed through graphs and tabulated values. We perceived that the velocity is more in Casson fluid than Williamson fluid, but the reverse trend is identified in the case of temperature and concentration fields. Moreover, we noted that the velocity of the fluid, skin friction, and Nusselt and Sherwood numbers are reduced for a growth in the magnetic field and it shows results of magnetic field, which gives rise a resistive force called Lorentz. Also, we observed that the rate of thermal and mass transfer coefficients was significantly larger in Casson fluid when compared to the Williamson fluid. The present results warrant the necessity of the investigation of various non-Newtonian fluids in different practical circumstances.
