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

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.

Automated summary

This study investigates the flow characteristics of a water-based hybrid nanofluid consisting of silver and alumina nanoparticles past a spinning disk. The effects of Brownian motion, activation energy, magnetic field, and thermophoresis are taken into account. The partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) through suitable correspondence transformations. The modeled equations are solved using a semi-analytical method known as HAM. Graphical representations of the nanofluid and hybrid nanofluid profiles are used. The findings show a decrease in the radial and tangential velocities of the nanofluids and hybrid nanofluid with an increase in the magnetic factor. The hybrid nanofluid exhibits higher growth and better thermal conductivity than the nanofluids due to the magnetic factor.
