Abstract
This paper focuses on the effects of DuFour, heat radiation, and chemical reaction on a two-dimensional natural convective flow of stable electrical magnetohydrodynamics (MHD) nanofluid across a permeable stretched sheet, in addition to the effects of suction. This work investigates the boundary layer flow dynamics of a nanofluid via a stretched sheet in the presence of a magnetic field, accounting for DuFour effects and chemical reactions. The non-linear partial differential equations were transformed into a non-linear ordinary differential equation by using the appropriate similarity transformation. The Keller box technique is used to numerically solve ordinary differential equations. Graphs are used to show variations in temperature, concentration, and velocity to different physical constraints. Raising the thermophoresis parameter (Nt) results in inferior concentration profiles due to a decrease in the Lewis number parameter (Le) and Brownian motion parameter (Nb). The concentration profile is reversible with temperature and decreases as the chemical reaction parameter increases. As we increase the Du levels, the temperature declines. The patterns in the altering rates of heat and mass transfer, as well as the skin-friction coefficient, are also analyzed using numerical data.”
