Abstract
Magnetic nanofluids exhibit remarkable ideas from their inherent ability to be externally controlled and to undergo changes in their physical characteristics. These changes, influenced by several factors such as volume concentration of nanoparticles and the strength of the applied magnetic field, those have a range of potential applications. With this understanding in mind, the current study adopts a model-based approach to probe the behavior of magnetohydrodynamic (MHD) stagnation point flow. This flow involves a hybrid nanofluid consisting of Fe3O4 (magnetite) and CoFe2O4 (cobalt ferrite) nanoparticles dispersed in water (H2O), through a heated shrinking Riga surface with velocity slip. The investigation integrates the influential conductivity models such as Hamilton-Crosser and Yamada-Ota models. Employing a numerical methodology, the dimensionless system is solved those are derived by implementing appropriate similarity transformation. Specifically, the Runge-Kutta-Fehlberg (RKF) procedure is synergistically employed in conjunction with the shooting method. The outcomes of the study reveals that; the enhanced volume concentration that enriches the physical quantities favours in augmenting the fluid temperature and the profile also enhances for the increasing thermal radiation.
