Transient radiative flow of hybrid nanofluid under slip effects over an impermeable spinning disk with porous material

Abstract

The hybrid nanofluid flow phenomena show their effective properties in various sectors likely; industries for better production of different products with their shape and size, cooling of electronic devices, drug delivery processes, etc. The present paper deals with the interaction of radiant heat on the flow of a hybrid nanofluid over a spinning disk embedding within a porous medium. The unsteady hybrid nanofluid in association with time-dependent magnetic field, radiant heat energies the flow phenomena. Further, the consideration of slip conditions at the surface has a greater impact on the thermal properties affecting the flow behaviour. The choice of a suitable similarity rule helps in transforming the designed model into set of dimensionless form. The set of nonlinear coupled differential equations are handled numerically via numerical technique. The computation is carried out for the standard values of the characterizing factors involved in the flow phenomena. However, the important observations are; the tangential velocity distribution retards for the increasing velocity slip whereas the axial velocity increases significantly. The fluid temperature augments for the enhanced thermal radiation at all points within the domain.
