Magnetically-driven nanofluid flow over a slippery-bended surface under thermal radiation and higher order chemical reaction

In this paper, nanofluid flow is considered on curved stretching surface under magnetic influence. Realistic velocity slip together with convective boundary condition is imported. The system is also blessed with radiation and higher order chemical reaction. Active and passive controls of nanoparticles are considered and under both boundary conditions the flow analysis is compared. Leading equations of the system is a set of partial differential equations which are transfigured by similarity variable into a set of highly nonlinear ordinary differential equations (ODEs). The system is solved by the Runge–Kutta fourth-order method (RK-4) with shooting technique. The simulation is done by MAPLE-2021 software. Outcomes are portrayed by several graphs and tables and comparison diagram for different conditions is also included. Velocity lines are compared for suction and injection effect but thermal and concentration profiles are compared under active and passive controls of nanoparticles. The velocity profile changed by 16.55% for higher magnetic profile and the mass transfer changed by 3.57% for actively controlled flow under velocity slip parameter. Chemical reaction parameter detained the concentration profile for both active and passive controls but gave lower magnitude for passively controlled flow.
