The impact of a chemical process on nanofluid flow above a nonlinearly extending surface has been examined. The study also investigates mass and heat transfer, which have potential applications in industrial coating processes. Commonly, no-slip conditions are applied at the boundary of the flow regime. Instead, we include the velocity- and thermal-slip effects as an added aspect of the investigation when the nanofluid flows
through a porous medium. The model is constructed using ordinary differential equations and after converted into partial differential equations via similarity transformations. A MATLAB program using the Keller-box method is employed to solve the modified equations. A Novel aspect of the combined effect of the magnetic field is the permeability parameter, and the chemical reaction was accounted for in the simulation of nanofluid flow over a nonlinear stretching surface. The study exhibits how different parameters affect the flow dynamics and flow features of nanofluid. It is seen that with an increase in a chemical reaction parameter, the reaction goes ahead at a faster rate, causing the concentration of the new product to increase. The research explores the impact of pertinent parameters on the dimensionless profiles of flow velocity, temperature, and mass concentration. Graphical representations are used to visualize the effects of key physical quantities in this study. The findings obtained are confirmed against previously published results.
