Modeling and theoretical investigation on Casson nanofluid flow over a curved stretching surface with the influence of magnetic field and chemical reaction

Abstract The current article explores the impact of magnetic effect on the Casson nanoliquid flow over a curved stretching sheet with the influence of chemical reaction. Further, the heat and mass transference characteristics are analyzed by means of Brownian motion, exponential heat source and thermophoresis effects. Governing equations of the described flow problem are transformed into ordinary differential equations by means of similarity variables. These reduced equations are numerically solved by Runge-Kutta-Fehlberg fourth-fifth (RKF 45) order scheme with shooting method. Results reveal that, the escalating values of curvature parameter improves the velocity gradient whereas, converse trend is detected in thermal gradient.
