A Spectral Simulation of Magnetohydrodynamic Convective Nanofluid Slip Flow with Newtonian Heating and Radiative Heat Transfer

Abstract

In this paper, we present a numerical analysis of natural convection boundary layer flow of a nanofluid over a stretching sheet under the influence of a variable magnetic field in the presence of nonlinear radiative heat transfer, hydrodynamic slip and Newtonian heating effects. The Brownian diffusion and thermophoresis effects are employed to describe the nanofluid flow model consisting of non-linear partial differential equations, which is transformed into a similarity form and then treated with the spectral local-linearization method (SLLM) to present an in-depth analysis of the flow and heat transfer characteristics of the fluid flow. The fluid flow problem finds applications in many engineering devices including geothermal heat source pump and in cooling of electronic devices and stretched wires.
