Chemically and thermally radiated Williamson MHD fluid over porous media with heat source-sink

Abstract

ABSTRACT The study of the stretching sheet has extensive applications in the field of engineering and technology. Hence, the objective of the present study is to deal with the impact of pertinent parameters on Williamson fluid across a stretchable nonlinear sheet when chemical reaction, varied thermal radiation, and heat source/sink are present. Partial differential equations are used to model the resulting scenario, and after adding the necessary similarity variables, a system of nonlinear ordinary differential equations is formed using flow equations. The reduced ODEs are tackled by applying the fourth-order RK-scheme together with shooting methodology, and the impacts of different system parameters are examined corresponding to the fluid’s velocity, energy, and concentration profile. The important findings are discussed using graphics and they are as follows: As magnetism increases, fluid velocity rises but falls with an increment in buoyancy; the temperature falls with a boost in Grashof number but rises with an inclination in Prandtl number; and fluid reaction concentration declines with the boost in chemical parameter and Schmidt number but rises with an increment in thermophoresis, heat source/sink, and Brownian motion parameter.
