Abstract
•Magnetohydrodynamic (MHD) nonlinear radiative flow of third grade nanofluid modeled.•Effects of heat generation/absorption and nonlinear convection are considered.•Aspects of chemical reaction and zero mass flux condition are introduced.•Brownian motion and thermophoresis phenomena are taken due to nanofluid.•Skin friction coefficient and local Nusselt number are tabulated and examined.
Nonlinear thermal radiation and chemical reaction in magnetohydrodynamic (MHD) flow of third grade nanofluid over a stretching sheet with variable thickness are addressed. Heat generation/absorption and nonlinear convection are considered. The sheet moves with nonlinear velocity. Sheet is convectively heated. In addition zero mass flux condition for nanoparticle concentration is imposed. Results for velocity, temperature, concentration, skin friction and local Nusselt number are presented and examined. It is found that velocity and boundary layer thickness are increasing for Reynolds number. Temperature is a increasing function of the heat generation/absorption parameter while it causes a decrease in the heat transfer rate. Moreover effect of Brownian motion and chemical reaction on the concentration are quite reverse.
