Entropy optimized Darcy‐Forchheimer slip flow of Fe3O4−CH2OH2 nanofluid past a stretching/shrinking rotating disk

Abstract

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 normalF e 3 O 4 − ( C normalH 2 O H ) 2 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.

“…In the current research, false( K e r o s e n e 0.25em o i l false) is considered as base fluid and false( G o − A g false) taken as hybrid nanoparticles, respectively (Figure 1). The governing boundary layer equations are 34–36 …”

Mixed Convection Magnetic Nanofluid Flow past a Rotating Vertical Porous Cone

“…The viscous dissipation effect has been used by Hamid et al (2022) to explore the flow phenomena of dusty MNF on the non-isothermal movable surface. Several other latest pertinent studies on MNF are extractable through this list: (Bhandari, 2021;Jalili et al, 2021;Mohamed et al, 2021;Nayak et al, 2021;Saranya et al, 2021;Uddin et al, 2021).…”

Assisting/opposing/forced convection flow on entropy‐optimized MHD nanofluids with variable viscosity: Interfacial layer and shape effects

“…In view of larger efficient, economical, and reliable systems containing heat transport phenomena, the augmentation of heat transfer (HT) via the amplification of TC of Newtonian and non-Newtonian nfs is needed. Choi 1 and some others [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] contributed the particle suspension mechanism to check the heat transfer rate (HTR) on several kinds of nps as Ag, Al 2 O 3 , CuO, carbon nanotubes (CNTs), Cu, MoS 2 , and TiO 2 . The controlled rate of HT is a prime factor in different engineering processes, where maintaining the system temperature is significant.…”
