Williamson MHD Nanofluid Slip Flow Over a Porous Melting Stretching Sheet With Activation Energy

ABSTRACT This study investigates Williamson nanofluid slip flow along a permeable melting nonlinear stretch sheet with activation energy, inclined magnetic field, heat source/sink, thermo‐solutal buoyancy forces, and thermophoretic velocity. Partial differential equations (PDEs) governing the physical phenomena are formulated and converted to nonlinear ordinary differential equations (ODEs) through similarity transformations. We applied the Runge–Kutta–Fehlberg fourth‐fifth order method (RKF45) for numerical solutions of ODEs. The key outcomes obtained indicate that the velocity profile decreases with a higher velocity slip parameter and angle of inclination, while it increases with the melting parameter. The temperature distribution declines with increasing endothermic/exothermic reaction parameter, activation energy parameter, and melting parameter, while the concentration field increases with the activation energy parameter and melting parameter.
