Joint Effects of Brownian Motion and Thermophoresis on Williams on Nano Fluid Flow Past a Stretching Sheet: MHD and Chemical Reaction Effects

Abstract

The objective of this study is to numerically solve the Williamson fluid flow equations across a non-linear stretching sheet while taking into account the existence of nanofluid particles, the effect of a magnetic field, and the impact of a chemical reaction. The energy and concentration equations account for the effects of thermophoresis and Brownian motion. The finite element approach is used to resolve the governing nonlinear equations of the fluid flow and the associated boundary conditions. Through graphical representations, the research explores the effects of several pertinent factors on the profiles of concentration, temperature, and velocity. Also shown in tabular form are the impacts of these factors on the skin-friction coefficient, Nusselt and Sherwood numbers, and heat and mass transfer rates. The correctness of the numerical model utilised in this research is then validated by comparison of the generated results with earlier findings.
