N2 - Ferrofluids are made out of nanoscale ferromagnetic particles and known as colloidal liquids suspended on a bearer liquid, normally water (H2O) or an organic solvent like kerosene. Ferrofluid is utilized in rotary seals, computer hard drives, loudspeakers, magnetic resonance imaging, and so forth. 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 (Formula presented.) nanofluid (nf) past stretching/shrinking rotating disk (RD) 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 RD. Enhanced Reynolds number peters out the entropy generation number for stretching RD, which was the goal of the study to be accomplished.
