This investigation unfolds the hydrothermal behavior and cooling process on the hybrid nanofluid spraying on an inclined revolving disk. The disk is presumed to rotate with the constant angular speed Ω. The hybrid nanofluid spraying is considered as thermally radiative and the existence of a magnetic field is presumed. A water-based graphene oxide and ferrous nanoparticles are considered to simulate the flow. The competence of hybrid nanofluid on the cooling process as compared to usual nanofluid is deliberated in detail. The foremost equations are made nondimensionalized followed by suitable similarity conversion. After that, those dimensionless equations are solved using the spectral quasi linearization method (SQLM). Residual error plots are depicted to explore the speedy convergence nature of SQLM. The impact of relevant factors is illustrated through various graphs and tables. The consequence extracts that the thermal profile has a linear relationship with nanoparticle concentration and radiation parameter, but it reveals an inverse relationship with the Prandtl number. Hybrid nanofluid exhibits comparatively higher heat transport as compared to usual nanofluid. We noticed that the radiation parameter, thickness parameter slow down the heat transport, while nanoparticle concentration amplifies such effect. Usual nanofluid shows relatively high heat transport reduction compared to hybrid nanofluid. The outcomes ensure the reduction at the rate of 2.68004 for hybrid nanofluid and 3.64286 for usual nanofluid The shear stress on the disk is marked to increase for both thickness parameters and magnetic field. This study has useful applications in the chemical and mechanical engineering process.
