Abstract : The present study investigates the flow of a second-grade liquid over a curved stretching sheet with the Soret, magnetic and Dufour effects. In addition, the Newtonian heating effect is taken into account in this simulation. The framed equations are transformed to a set of nonlinear ordinary differential equations using suitable similarity variables, and then numerically solved using Runge–Kutta–Fehlberg's fourth fifth order approach and the shooting technique. The impact of dimensionless factors on the flow, thermal, and concentration fields are interpreted and explained in detail by using suitable graphs. The increase in the Newtonian heating parameter increases the heat transfer coefficient which increases the heat transfer of both second grade and Newtonian fluids. Furthermore, Newtonian liquid is significantly influenced by Newtonian heating parameter and exhibits enhanced heat transfer. The concentration profile of Newtonian fluid is significantly influenced by Soret and Dufour numbers and rises quicker than the non-Newtonian fluid.
