Stability Analysis of Buoyancy Magneto Flow of Hybrid Nanofluid through a Stretchable/Shrinkable Vertical Sheet Induced by a Micropolar Fluid Subject to Nonlinear Heat Sink/Source

Abstract

The utilization of hybrid nanofluids (HNs) to boost heat transfer is a promising area of study, and thus, numerous scientists, researchers, and academics have voiced their admiration and interest in this area. One of the main functions of nanofluids is their dynamic role in cooling small electrical devices such as microchips and associated gadgets. The major goal of this study is to perform an analysis of the buoyancy flow of a shrinking/stretching sheet, whilst considering the fascinating and practical uses of hybrid nanofluids. The influence of a nonlinear heat source/sink induced by a micropolar fluid is also inspected. Water-based alumina and copper nanoparticles are utilized to calculate the fine points of the fluid flow and the features of heat transfer. The governing equations are framed with acceptable assumptions and the required similarity transformations are used to turn the set of partial differential equations into ordinary differential equations. The bvp4c technique is used to solve the simplified equations. Dual solutions are presented for certain values of stretching/shrinking parameters as well as the mixed convective parameter. In addition, the shear stress coefficient in the first-branch solution (FBS) escalates and decelerates for the second-branch solution (SBS) with the superior impact of the magnetic parameter, the mass transpiration parameter, and the solid nanoparticles volume fraction, while the contrary behavior is seen in both (FB and SB) solutions for the larger values of the material parameter.

The Influence of Magnetic Fields on Electrophoretic Processes in Magnetic Colloids with Different Stabilization Mechanisms

“…As was mentioned above, we previously studied the features of deposit formation during the evaporation of flat drops of a magnetic fluid located on a solid conducting substrate [36]. It was found that the impact of an electric field created by applying a voltage between the substrate and a needle electrode placed in the center region of the drop…”

“…In the first case, stabilization is achieved by the steric repulsion of amphiphilic molecules adsorbed on the surface of presumably uncharged magnetite particles, while in the second case, stability is maintained mainly due to the electrostatic repulsion of double electrical layers formed on the boundary of the colloidal particles. The latter factor determined that the majority of charge transfer processes and electrokinetic phenomena studies were conducted in waterbased systems [33][34][35][36], but still, much attention was also paid to the study of the electrical properties of magnetic fluids based on hydrocarbon media. The use of hydrocarbon-based magnetic fluids as a dielectric medium can facilitate the use of EHD flows, so in this case it becomes possible to control the process through the additional action of a magnetic field.…”

“…al [42] described the effect of radiation on the rotating flow of carbon nanotubes. Literature such as [43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] involves the study of the flow of nanotubes in a rotating frame of reference.…”

Computational Examination of Heat and Mass Transfer Induced by Ternary Nanofluid Flow across Convergent/Divergent Channels with Pollutant Concentration

“…Khan et al [15] examined the water-based alumina nanofluid implanted in a porous media with buoyancy force that caused a two-dimensional stretched wall jet to transfer heat in fluid flow. Khan et al [16] studied the stability analysis and the movement of two distinct types of nanoparticles present in fluid across an extendable/shrinkable vertical surface produced by a micropolar fluid with an inconsistent heat source/sink. Kumar et al [17] studied the hybrid ferrofluid layer flow and heat transmission in the presence of radiation and erratic heat sources and sinks.…”
