Entropy optimized Darcy-Forchheimer slip flow of Fe3O4-(CH2OH)2
nanofluid past a stretching / shrinking rotating disc: Application to
electric machines
Abstract
The present article reveals the extent of effectiveness available from
the investigation on entropy generation, thermal radiation, viscous
dissipation on Darcy-Forchheimer convective slip flow of Fe3O4-(CH2OH)2
nanofluid past stretching/shrinking rotating disk subject to suction.
The concepts of different parameters and their effects on velocity,
temperature, entropy generation number and Bejan number profiles have
been elaborated in this explanatory paper. The explanations using graphs
and numerical tables help smoothen the understanding and strengthen the
interpretations of the results of the study. The major eye-catching
outcome of the study is that the augmented slip parameter undermines the
tangential velocity and fluid suction invites a diminutive radial
velocity as well as temperature distribution due to stretching/shrinking
rotating disk. Enhanced Reynolds number peters the entropy generation
number out for stretching rotating disk which was the goal of the study
to be accomplished.
