Abstract
Mixed convective flow over a revolving sphere is of immense interest in several industrial and engineering applications starting from polymer deposition, electrolysis management, drug transport, spin-stabilized missiles, cooling of spinning machinery slices, etc. Hybrid nanofluid exhibits promising efficiency in heat transport compared to mono nanofluid. They are widely introduced in nuclear power plants, solar collectors, heat exchangers, microfluidic heat sinks, etc. Such unique promising applicative features drive this investigation to analyse the magnetized mixed convective unsteady Ag/MgO-water hybrid nanofluid stream over a whirling sphere near the stagnation zone. Moreover, the nanofluid motion is treated as thermally radiative. The foremost flow profiles are made dimensionless using appropriate similarity translation. The renovated equations associated with the boundary restrictions are treated numerically. Several schematics are extracted to reconnoiter the requisite noteworthy influence of flow parameters on thermal, velocity, heat transport, and skin frictional profiles. Consequences indicate the increase in x-direction velocity for the unsteadiness parameter and mono nanofluid exhibits higher velocity compared to hybrid nanofluid, while the reverse is detected for z-direction velocity. Thermal enhancement is assured for radiation parameters and nanoparticle concentration, where hybrid nanofluid illustrates a higher magnitude. Heat transport is also higher for hybrid nanofluid compared to the usual nanofluid.
