MHD convective non-Darcy flow of a nanofluid through a porous stretching sheet with thermal buoyancy and chemical reaction

Abstract

In this article, magnetohydrodynamic (MHD) the two-dimensional stagnation-point convection flow over a nanofluid through a porous medium due to a solar energy stretching sheet is investigated theoretically. Heat transfer subject to thermal radiation, viscous dissipation, an applied magnetic field, thermal buoyancy, and convective boundary conditions is considered. The governing boundary layer equations are reduced into ordinary differential equations by a similarity transformation. The transformed equations are solved numerically by using an efficient numerical shooting technique with a fourth-fifth order Runge–Kutta method scheme. The effects of the external parameters as jets flow, thermal convective, and mass convective on the flow field and heat transfer characteristics were obtained and discussed. Finally, the results obtained agree with the practical results and applicable in the related fields, especially, medicine, biochemistry, pharmacology, … , etc.
