Homotopic solution of the chemically reactive magnetohydrodynamic flow of a hybrid nanofluid over a rotating disk with Brownian motion and thermophoresis effects

Abstract

Due to the synergetic effects of several types of nanomaterials, the primary goal of the hybrid nanofluid is to enhance the energy transport capabilities over a base fluid. Hybrid nanofluids have a wide range of applications in the industrial, technical, and medical industries, including solar heating systems, food processing, microchannel heat sinks (MCHS), and medicines. In this article, the researchers have investigated the water‐based hybrid nanofluid flow comprising silver and alumina nanoparticles past a spinning disk. The effect of Brownian motion, activation energy, magnetic field, and thermophoresis are taken into account. The PDEs are transformed into ODEs by means of suitable correspondence transformations. The modeled equations are solved by using a semi‐analytical method known as HAM. Graphical representations of the nanofluid and hybrid nanofluid profiles are used. The current findings are contrasted with those that have already been published and are confirmed to be remarkably comparable. The outcomes showed that the radial and tangential velocities of the nanofluids and hybrid nanofluid reduced as the magnetic factor augmented. Nanofluids and hybrid nanofluid surface drag is increased by magnetic factor. Hybrid nanofluid exhibits higher growth due to the magnetic factor than nanofluids do. The heat transmission rates of nanofluids and hybrid nanoliquid have grown as a result of the thermophoresis factor and nanoparticle volume fractions. In comparison to nanofluids, the hybrid nanofluid also possesses a better thermal conductivity.

Electroosmotic microchannel flow of blood conveying copper and cupric nanoparticles: Ciliary motion experiencing entropy generation using backpropagated networks

“…Because of the small size of the nanoparticles, Brownian motion is the major mechanism of particle dispersion in nanofluids. Rashid et al [21] demonstrated a homotopic solution to a hybrid nanofluid's chemically reactive magnetohydrodynamic flow across a rotating disc with Brownian motion and thermophoresis effects. Kalpana et al [22] used a computer method to study the magnetohydrodynamic boundary layer flow of a hybrid nanofluid exhibiting thermophoresis and Brownian motion in a nonuniform channel.…”

Performance of variable characteristics on MHD Jeffery nanofluid over spinning disk with Cattaneo‐Christov heat flux and microswimmers

“…Von-Karman [14] for the first time performed research on rotating disk. Rashid et al [15] studied the water-based hybrid nanofluid flow containing silver and alumina nanoparticles over a spinning disk with binary chemical reaction and activation energy. Their results show that the hybrid nanofluid has better thermal conductivity than mono nanofluid.…”

Numerical investigation of the magnetohydrodynamic hybrid nanofluid flow over a stretching surface with mixed convection: A case of strong suction

“…They proposed a theoretical model that accounts for the basic role of dynamic nanoparticles in nanofluids and uncovered an important factor in size-dependent conductivity between solid/solid composites and solid/liquid suspensions, as well as nanoparticle size and temperature. Rashid et al 4 examined the comparison of hybrid nanofluid past a rotating disk. Chon et al 5 demonstrated an experimental relationship for A l 2 O 3 nanofluid heat transfer as a function of nanoparticle size (varying from 11 to 150 nm nominal diameters) over a wide temperature range (21°C–71°C).…”
