Abstract
The present investigation reveals the flow phenomenon and thermal variations of unsteady radiative nanofluid flow induced by the magnetized spinning disk. The presence of partial slips at the disk surface has been executed. Graphene nanoparticle with base medium water is treated as a working fluid. The surface of the disk is taken as permeable to include the suction/injection effect on the flow profile. Moreover, the influence of nanoparticle diameter and liquid-solid interfacial layer is introduced at a molecular level to disclose the thermal integrity of the flow. Similarity variables are adopted to reduce the core equations into non-dimensional form and then a shooting-based Runge-Kutta-Fehlberg (RKF) scheme is executed to achieve the solutions. Nanofluid velocity reduces for unsteadiness parameter and velocity slip. Temperature diminishes for increasing nanoparticle diameter but reduces for nanolayer ratio. Heat transmission amplifies for thermal radiation and nanolayer ratio but declines for nanoparticle diameter. Approximately, we detected 84.61% enhancement in heat transfer for nanolayer.
