| Summary: | Many researchers have been captivated by the ability of hybrid ferrofluid to increase heat and mass transmission, leading them to further examine the working fluid. This study is essential for figuring out how Fe3O4-CoFe2O4/H2O hybrid ferrofluid would behave thermally and massively when physical factors like a greater degree of chemical reaction (n) and slip boundary conditions are present through mixed convection stagnation point flow in Fe3O4-CoFe2O4/H2O hybrid ferrofluid toward a permeable vertical flat plate embedded in Darcy porous medium. The complexity of the partial differential equation for heat, flow, as well as mass transfer is reduce through similarity transformation into a system of ordianry differential equation, before being numerically solved using the built-in solver bvp4c in MATLAB for various values of the governing parameters. Dual solutions (first and second solution) are obtained as result produced in regions of opposing and assisting flow. Hybrid ferrofluids with additional CoFe2O4 nanoparticles have a higher heat transfer rate than ferrofluids and base fluid (water). Furthermore, a different order of chemical reaction greatly influences the mass transfer rate. Note that the presence of thermal and concentration slips reduce the heat transfer and mass transfer rate, accordingly, and delay the boundary layer separation.
