摘要

This work examines the numerical representation of boundary layer flow across a surface using the Maxwell model. Mass transfer, heat generation, Arrhenius activation energy, non-Darcy effect, Dufour effect, and thermal radiation are all discussed in this study. The required similarity transformations are applied in primary equations, and solutions are obtained using the built-in bvp4c program. The comprehensive agreement with previously reported data demonstrates the efficacy of the numerical technique. Several factors, such as the non-Darcy parameter, Deborah number, magnetic parameter, Dufour parameter, chemical reactions, activation energy, etc., are highlighted in the tables and graphical representations of the data. Figures demonstrate that the Deborah number increases fluid velocity while the non-Darcy and magnetic parameters cause it to slide. The Dufour number, Eckert number, and thermal radiation contribute to an increase in the temperature profile, while the Prandtl number causes a reduction due to velocity slip effects. Activation energy increases the concentration field, whereas chemical reactions lead to its reduction.
