A numerical investigation has been conducted on the flow of a nanofluid over an exponentially stretching surface, a configuration relevant to many industrial heat and mass transfer applications. By applying appropriate similarity transformations, the governing partial differential equations are reduced to a set of dimensionless ordinary differential equations. These nonlinear equations are solved numerically using the fourth-order Adams–Moulton method integrated with a shooting technique to ensure accuracy and stability. The validity of the computed results is established by benchmarking them against previously published findings in the literature. Key parameters influencing the flow are illustrated and discussed through graphical representations. The study's overall findings support the conclusion that increasing the Hartmann number, Schmidt number and thermal stratification parameter reduces the thermal boundary layer thickness. Moreover, enhanced solutal stratification and chemical reaction parameters are found to suppress the nanoparticle concentration. Engineering quantities like the skin friction coefficient, Nusselt number and Sherwood number are also computed and analysed, providing insights into optimising nanofluid-based thermal systems under complex boundary conditions.References
