Abstract

This study investigates the boundary layer stagnation point flow of hydromagnetic tangent hyperbolic nanofluid over a nonlinear plane in a porous device under the influence of a prescribed power law thermal condition. The modelled partial differential equations outlining the flow problems are translated into ordinary ones using suitable similarity transformation variables. The resultant equations are numerically solved by the shooting technique together with Runge-Kutta Fehlberg scheme. The effects of the various physical parameters are graphically analyzed and deliberated. The obtained results are validated with related existing studies in the limiting position and found to be in perfect agreement. The results indicate that the hydrodynamic boundary layer structure together with velocity profile decelerate when Darcy and magnetic parameters increase whereas the temperature profile appreciates with these terms. Temperature ratio or wall heating parameter triggers a rise in the heat transfer while the thermal field grows with an increase in the magnitude of thermophoresis and Brownian motion terms. Also, the heat transfer at the surface is a decreasing function of these terms.
