13 Dufour and Soret effects on nanofluid over an exponentially stretching sheet with chemical reaction

Sangamesh
Abstract
This research investigates the behavior of nanofluid flow past an exponentially stretching sheet at the stagnation point, considering cross diffusion and chemical reaction effects. The coupled nonlinear boundary-value problem arises due to the interplay of Brownian motion and thermophoretic effects. The Soret and Dufour effects, along with chemical reactions, find applications in various areas of fluid mechanics, including combustion systems, petrochemical industry, biological systems, environmental engineering, and energy conversion systems. The partial differential equations (PDEs) are transformed into ordinary form using appropriate similarity variables. These equations are numerically solved using the Bernoulli wavelet method (BWM) in MATHEMATICA 12. The obtained results exhibit excellent agreement with the previous studies that focused on different special cases of the problem. A parametric analysis of physical constraints is presented and numerical results are illustrated graphically. The influence of intensified Brownian motion and thermophoretic effects is observed through increased temperature and expansion of the thermal boundary layer (TBL). With higher chemical reaction rates, there is a notable reduction in concentration. It is observed that a decrease in the Soret effect leads to a rise in the width of the thermal boundary layer, while the concentration profile exhibits the opposite trend.
