Dual solutions in MHD stagnation point flow of nanofluid induced by porous stretching/shrinking sheet with anisotropic slip

Abstract

In this article, the steady three-dimensional stagnated flow induced by a porous moving system is investigated. The flow field and thermal distribution are subject to anisotropic slip and a magnetic field. The existing nonlinear equations are unraveled numerically using a bvp4c code in Matlab. The impact of various parameters on flow profiles temperature surface friction and surface heat transfer rate is put together in graphs and tables. The accomplished results depict that the velocity fields enhance for both S < 0 (suction) and S > 0 (injection). Similarly, it is noticed that surface shear stress and heat transfer possess stronger behavior for the case of injection. The behavior of temperature fields is opposite for upper and lower solutions when checked for the Prandtl number Pr. Stability analysis shows that the primary solution is stable and substantially feasible, whereas the second solution is not stable. The velocity h(?) decays with the magnetic field for both solutions. � 2020 Author(s).
