Abstract This study analyzes the hybrid nanofluid flow, which is a mixture of copper (Cu) and aluminum oxide (Al₂O₃) nanoparticles suspended in water (H₂O). The hybrid nanofluids are crucial for optimizing thermal management systems, such as heat exchangers, cooling devices, car engines, and electronics, where efficient heat transfer is a dominant feature. The considered fluid flows over an inclined surface within a porous medium. The impact of several physical phenomena on the heat transfer and flow characteristics of this nanofluid is examined. The fluid model involves mixed convection, where both forced and natural convection contribute to the heat transfer process. It also investigates the effects of magnetohydrodynamics, thermal radiation, Joule heating and non-uniform heat source/sink on the considered flow. To model this complex system, a set of partial differential equations (PDEs) is formulated. These PDEs are typically challenging to solve directly due to their complexity, so the similarity transformations are employed. These similarity transformations simplify the PDEs by reducing them to a set of ordinary differential equations (ODEs), making the problem more manageable and solvable. To solve the reduced system of ODEs, a MATLAB’s bvp4c function, is utilized to handle the boundary value problem. This function helps in obtaining numerical solutions for the velocity and temperature profiles of the fluid under the specified conditions. The results from this numerical analysis provide insights into the velocity distribution, temperature profile, skin friction coefficient, which quantifies the drag force exerted by the fluid on the surface, and the Nusselt number, which is a dimensionless measure of the convective heat transfer rate, The velocity profile experiences an upsurge for the rise in stretching parameter and inclination angle. The temperature of the hybrid nanofluid is improved by the Biot number, heat source/sink parameters and Eckert number.
