Summary: This study investigates the ferrohydrodynamic interaction of hybrid magnetic nanoparticles in an ethylene glycol plus water mixture flowing over an inclined stretching sheet, taking into account the magnetic dipole effect. The results indicate that an increase in the inclination angle and mixed convective parameter enhances the velocity profile and Nusselt number, whereas the ferrohydrodynamic interaction and ferroparticle volume fraction exhibit the opposite trend. Furthermore, the study reveals that under certain conditions, the presence of magnetic oxide and cobalt iron oxide suspended in an ethylene glycol plus water mixture effectively reduces the heat transfer rate.

Summary: The study investigates the post-impact hydrodynamics of ferrofluid droplets on superhydrophobic surfaces in the presence of a horizontal magnetic field. Various dynamics were observed by controlling the impact parameters and magnetic field strength, leading to findings such as the suppression of droplet rebound and the formation of unstable liquid lamella. The asymmetrical spreading of droplets due to the Lorentz force was highlighted as a key factor influencing the impact outcomes.

Summary: This study investigates the stability of a ferrofluid with a fairly arbitrary non-uniform magnetic susceptibility between two parallel walls, subject to a non-uniform magnetic field acting normal to the walls. It is found that adding a constant field can suppress parallel instabilities, while stability can be achieved by applying a rapidly rotating field.

Summary: This paper discusses the analysis of incompressible Non-Newtonian blood flow in an elastic artery with fluid structure interaction, considering the impact of Power law index, Reynolds number, and Hartmann number. The results show a significant increase in wall shear stresses with an increase in Power law index and Hartmann number, while an expected decrease in wall shear stresses with an increase in Reynolds number. Additionally, the load on the walls increases as the Hartmann number and power law index increase, showing different responses for different types of shear thinning or thickening cases.

Summary: Inspired by liquid bridge bearings, a ferrofluid (FF) bearing is proposed in this work. The bearing consists of two plates with FF sandwiched between them and a cylindrical magnet implanted in the lower plate to restrain and position the FF. The carrying capacity of the liquid bridge and FF bearing is tested and compared, and the results show that the FF bearing provides a higher maximum force and more stable supporting performance due to the magnetic field effect.

Summary: This study numerically simulates the time-based unsteady flow of Casson-Williamson nanofluid over a magnetic dipole enabled curved stretching sheet, considering factors such as thermal radiation, Joule heating, an exponential heat source, homo-heterogenic reactions, slip, and melting heat peripheral conditions. The analysis shows that the thermal buoyancy component enhances the velocity regime, while the melting parameter and radiation parameter have counterintuitive effects on the thermal profile. The ferrohydrodynamic interaction parameter slows down the velocity distribution of the nanofluid flow. Graphical representations of streamlines and isotherms are provided to demonstrate the flow and heat distribution.

Summary: This study considers the two-dimensional flow of Sutterby-Casson fluid over an exponentially curved sheet. The governing equations are reduced to a dimensionless system using boundary layer approximations and solved numerically. The results show that an increase in the Brownian factor leads to an increase in concentration, while an increase in the energy activation factor has a smaller impact on the Nusselt factor and mass transfer factor. The reaction of the chemical factor affects mass transfer, friction factor, and heat transfer.

Summary: Magnetic hyperthermia can be regulated in the blood by using magnetic nanoparticles and changing the nature of the magnetic field. This research examines the effects of uniform and non-uniform magnetic fields on bio-magnetic fluid and nano-bio-magnetic fluid under hyperthermia. The study shows that a uniform magnetic field increases temperature locally but decreases the overall temperature, while a non-uniform field decreases both local maximum and average blood temperature.

Summary: This study aims to enhance heat transformation by modeling and analyzing the biomagnetic fluid flow and heat transfer, specifically investigating the flow of blood with magnetic particles induced by a stretching cylinder with linear and nonlinear stretching velocities. The collection of partial differential equations is transformed into a theoretically stated ordinary differential system using similarity transformations. The results show that variation in velocity and temperature distributions due to an increase in the ferromagnetic interaction parameter and the size of magnetic particles. Moreover, an increase in particle diameter leads to an increase in skin friction while reducing the rate of heat transfer.

Summary: This study investigates the effect of a magnetic field on the two-dimensional boundary layer heat transfer in an electroconductive Newtonian fluid. The magnetic induction effects are induced by the relatively high Reynolds number. The temperature and velocity of the stretching surface are inversely related to its distance from the steady edge. Non-dimensional major equations are obtained through a local non-similarity transformation. A numerical solution of the resulting boundary value problem is obtained using a sixth-order Runge-Kutta integration scheme and Nachtsheim-Swigert shooting iterative technique. The study provides valuable insights into the physical impacts of fluid parameters and the distributions of skin friction coefficient and local Nusselt number.

Summary: This research aims to investigate how temperature-dependent fluid properties can improve the heat transfer efficiency and performance evolution of hybrid nanofluid in the presence of a transverse magnetic field. The study explores the effects of varying the magnetic field strength and the volume fraction of Fe3O4 nanoparticles on fluid motion and energy transport. The results show that increasing the volume fraction of Fe3O4 enhances heat generation and thermal conductivity, leading to a rise in thermal boundary layer, while increasing the variable Prandtl number significantly improves the heat transfer rate.
