Abstract: This study examined a two-dimensional flow of Casson fluid on an exponentially stretched surface subjected to a transverse magnetic field in the presence of chemically reactive species. The physical characteristics of the problem are explored through mathematical modeling in the form of partial differential equations (PDEs). These equations are nondimensionalized using suitable similarity variables to obtain a set of ordinary differential equations (ODEs). The nonlinear high-order ODEs were then reduced to a coupled first-order system of ODEs. The fourth-fifth order Runge–Kutta–Fehlberg method was used along with the shooting techniques to examine the flow problem. Numerical results for the skin friction coefficient, the Nusselt number, and the Sherwood number were obtained, tabulated, and discussed. Graphical results for the velocity, temperature, and concentration profiles depicting the effects of various controlling parameters on the flow are displayed. The study showed that the rate of heat and mass transfers diminished while the skin-friction coefficient increased with increasing Casson parameter. The diminishing velocity profiles near the surface resulted in thermal enhancement within the boundary.
