Abstract:
The hydromagnetic °ow of magnetite–water nano°uid due to a rotating stretchable disk
has been numerically assessed. The nano°uid °ow has been modeled utilizing the adapted
Buongiorno model that considers the volume fraction-dependent e®ective nano°uid properties
and the major slip mechanisms. In addition, experimentally gleaned functions of e®ective
dynamic viscosity and e®ective thermal conductivity are deployed. The modeled equations are
transformed into a ¯rst-order ODEs scheme employing Von K arm an's similarity conversions
and then resolved via the Runge–Kutta algorithm through the shooting technique. The impact
of pertinent terms over the physical quantities, nanoliquid temperature and nanoliquid concentration is explained with the support of graphs. Results show that rising volume fraction of
magnetite nanoparticles (NPs) and magnetic ¯eld term enhance the drag force. Mass transport
rate is demoted with augmenting values of magnetic ¯eld parameter whereas is promoted
with increase in Schmidt number. Further, it is detected that the changes in stretching
strength parameter are directly proportional to Nusselt number and inversely proportional to
the thermal ¯eld. The ¯ndings of this numerical analysis have applications in spin coating,rotating disk reactors, storage devices for computers, food processing, and rotating heat
exchangers.
