Radiative nanofluid flow and heat transfer over a non-linear permeable sheet with slip conditions and variable magnetic field: Dual solutions

Objective: This paper addresses numerical investigation of steady, magneto-hydrodynamic boundary-layer slip flow of a nanofluid past a permeable stretching/shrinking sheet with thermal radiation using RKF45 with shooting technique. The effect of viscous dissipation, suction/injection, Brownian motion, thermophoresis, partial velocity slip and thermal slip is taken into account and controlled by the non-dimensional parameters. Results and conclusions: The dual solutions are obtained for the skin friction, Nusselt number, temperature and nanoparticle volume fraction with pertinent parameters in the domaindvc; (chi(c,) infinity) and (s(c,) infinity). The study shows that the Nusselt number decreases with an increase in thermophoresis parameter Nt and thermal slip parameter delta but increases with thermal radiation R and Prandtl number Pr.
