MHD stagnation point flow of viscoelastic nanofluid with non-linear radiation effects

This article addresses the MHD stagnation point flow of a viscoelastic nanofluid towards a stretching surface with nonlinear radiative effects. The nanofluid model consists of Brownian motion and thermophoresis. Heat transfer is studied by employing convective condition at the stretching surface. A newly constructed condition for heat transfer is imposed. The relevant problems are modeled by considering nonlinear thermal radiation. Similarity transformation is utilized to reduce the nonlinear partial differential equations into coupled nonlinear ordinary differential equations. The convergent solutions for velocity, temperature and concentration equations are developed. Graphical results are drawn for the velocity, temperature, concentration, skin friction coefficient and Nusselt number. It is noticed that skin friction increases for a larger magnetic parameter.
