Dissipative magnetic ohmic heating influence on radiative nanofluid flow about a permeable stretching sheet under a porous medium with heat source

Abstract

The present numerical analysis describes the influence of dissipative magnetic Ohmic heating on the radiative magnetised nanofluid flow about a permeable stretching sheet under porous medium and thermal source/sink effects numerically. Produced steady-state Navier-Stokes conservation equations are highly nonlinear, coupled and which are rendered non-dimensional through appropriate similarity transformations. A Runge–Kutta scheme with shooting technique is implemented to produce the similarity solutions. Increased Lorentz force field decreases the velocity field. Nanofluid velocity significantly decreasedadjacent to the solid sheet for the increasing porous parameter. Enhancing thermal absorption number decreases the thermal boundary layer thickness. The novelty of the current investigation is to generalise the former studies by incorporating the magnetic Ohmic heating; viscous dissipation, radiation, porous number, Brownian motion and thermophoresis parameters and producing more refined nanofluid flow definition. A comparative study with former results also included to quantify the guarantee of the produced similar results.
