Abstract
This study investigates the effects of first-order chemical reaction, thermophoresis, electrification, and Brownian motion on nanoparticles within a free convective nanofluid flow past a vertical plane surface, focusing on skin friction, heat and mass transfer. The unique combination of chemical reaction and electrification effects sets this study apart from previous research on nanofluid flow. By utilizing similarity functions, the governing PDEs of the flow are converted into a system of locally similar equations. These equations are then solved using MATLAB's bvp4c function, incorporating dimensionless boundary conditions. The findings are verified through a comparison with previous studies. Graphical illustrations show the numerical explorations for concentration, velocity, and temperature profiles in relation to the electrification parameter, thermophoresis parameter, chemical reaction parameter, and Brownian motion parameter. The computational results for heat transfer, mass transfer and dimensionless skin friction coefficients are presented in tabular form. The primary finding indicates that the electrification parameter accelerates heat transfer, while the electrification parameter, Brownian motion parameter, and chemical reaction parameter enhance the rate of mass transfer from the plane surface to the nanofluid. This indicates encouraging potential for cooling plane surfaces in manufacturing industries.
