Abstract
The increasing demand of sustainable energy technologies and climate-resilient engineering systems has increased interest in advanced heat transfer fluids capable of enhancing thermal performance and energy utilization. The chemically reacting nanofluid passing through the porous bed are experienced in the solar thermal management systems, thermal management technologies, geothermal energy extraction and transportation in environmental system. This study can be used in the climate modeling to mitigate the climate change. Therefore, this study investigates the steady magnetohydrodynamic (MHD) and chemically reactive incompressible flow of a second-grade nanofluid over an inclined porous stretching surface embedded in a porous medium. The proposed problem is given form of partial differential equation and then transformed using an appropriate similarity variable to convert into ordinary differential equations. The obtained ordinary differential equations are solved using MATLAB built in numerical solver bvp4c. The numerical results are illustrated through graphical profiles and tabulated data to demonstrate the influence of key dimensionless parameters, including the mixed convection parameter, second-grade fluid parameter, porosity parameter, thermophoresis parameter, Brownian motion parameter, magnetic field parameter, chemical reaction parameter, suction/injection parameter, Schmidt number, Prandtl number, and inclination angle. The analysis reveals that increasing the chemical reaction parameter reduces the velocity, temperature, and concentration distributions within the boundary layer. Conversely, an increase in the mixed convection parameter enhances the fluid velocity while simultaneously reducing both temperature and concentration profiles. Furthermore, comparison with previously published results shows excellent agreement, confirming the accuracy and reliability of the present analysis.
