Numerical solution of EMHD GO-Fe3O4/H2O flow and heat transfer over moving riga plate with thermal radiation and heat absorption/generation impacts

The importance of thermal radiation impacts on electromagnetohydrodynamics (EMHD) hybrid nanofluid movement heat transference towards stretching/shrinking surface is investigated. The influences of external effects such suction, heat absorption and generation are also being considered. The hybrid nanofluid chosen for exploration is Graphene Oxide (GO) and Iron Oxide (Fe304) as nanoparticles, while water (H2O) is a base fluid. The mathematical modelling in partial differential equations (PDEs) is formulated to ordinary differential equatims (ODEs) for simplicity using an aprropriate similarity variable. The solution of the reduced ODEs is then computed with the help of bvp4c solver built-in MATLAB software. The findings reveal that the magnetic field augmented velocity profile, while thermal affects the temperature profiles to amplify. The heat generation and absorption upsurged the head transfer for GOFe3O4/H2O with accompanying effects like plate thickness. It is also worth mentioning that GOFe3O4/H2O enhanced skin friction and heat transfer by about 3.2% and 1.6%, respectively, more than Fe304/H20.
