Abstract

Magnetohydrodynamic (MHD) radiative chemically reactive mixed convection flow of a hybrid nanofluid (Al₂O₃–Cu/H₂O) across an inclined, porous, and stretched sheet is examined in this study, along with its unsteady heat and mass transport properties. The hybrid nanofluid’s enhanced heat transfer efficiency is a major benefit in high-performance engineering applications. It is composed of two separate nanoparticles suspended in a base fluid and is chosen for its improved thermal properties. Thermal radiation, chemical reactions, a transverse magnetic field, surface stretching with time, injection or suction through the porous medium, and the effect of inclination, which introduces gravity-induced buoyancy forces, are all important physical phenomena that are taken into account in the analysis. A system of nonlinear ordinary differential equations (ODEs) is derived from the governing partial differential equations for mass, momentum, and energy by applying suitable similarity transformations. This simplifies the modeling procedure. The bvp4c solver in MATLAB is then used to numerically solve these equations. Different governing parameters modify temperature, concentration, and velocity profiles in graphs and tables. These factors include radiation intensity, chemical reaction rate, magnetic field strength, unsteadiness, suction/injection velocity, inclination angle, and nanoparticle concentration. A complex relationship between buoyancy and magnetic factors makes hybrid nanofluids better at heat transmission than regular ones. Thermal systems including cooling technologies, thermal coatings, and electronic heat management benefit from these findings.
