Summary: This study analyzed a micro-polar nanofluid in a rotating system with electric and magnetic fields. The results showed that increasing the magnetic parameter led to an increase in velocity and micro-rotation velocity. Additionally, the velocity increased with increasing rotation parameter. The temperature distribution was affected by the inverse relationship between Reynolds and Schmidt numbers, as well as the direct effect of Prandtl number and Brownian motion. Furthermore, concentration value decreased with an increase in the thermophoretic parameter and Reynolds number. The study demonstrated the accuracy and efficiency of the method used.

Summary: The term "vortex" refers to a region in a fluid where the flow spins around an axis line. Vortices can twist, stretch, move, and interact, and they are important to researchers due to their presence in various flows. Magnetic field effects are important in various technical applications, while hybrid nanofluids have higher thermophysical properties and are commonly used in thermal systems.

Summary: In this study, the numerical investigation of two-dimensional incompressible hybrid nanofluid flow was conducted between two parallel sheets, taking into account the magnetic field and varied thermal conductivity. The solid particles considered were magnetite (Fe3O4) and carbon nanotubes (CNTs) dispersed in water. The effects of a heat source/sink were also analyzed. Non-dimensional ordinary differential equations (ODEs) were obtained through similarity reduction, and the Runge-Kutta-Fehlberg (RK4) method and shooting procedure were used for numerical solution. The analysis revealed the influences of controlling parameters on temperature, velocity, Nusselt number, and skin friction of the working fluid. The use of mass-based method provided reliable results for flow and heat transfer analysis with heat generation and oblique magnetic field. The results showed a reduction in heat transfer due to temperature-dependent thermal conductivity and an oblique magnetic field, and the highest temperature distribution was observed in the presence of spherical solid particles and a horizontal magnetic field.

Summary: Vortices are important and attract the attention of many scientists in fluid dynamics. The complex dynamics of a Lorentz force in a hybrid fluid containing Silver (Ag) and Titanium dioxide (TiO2) nanoparticles are studied. The numerical solution is determined using the alternating direction implicit (ADI) method. It is found that increasing magnetic fields result in the degeneracy of primary vortices and the formation of new smaller vortices along the vertical walls. Increasing Reynolds number leads to the appearance of new vortices with different strengths and rotational directions.

Summary: This research aims to understand the effect of a magnetic field generated by a nearby dipole on the flow of nanofluid in a cavity. The study shows that the dipole can create new vortices in its vicinity and enhance the Nusselt number. The Reynolds number reduces the Nusselt number along the lower wall and affects the strength of vortices near the dipole location. Increasing the strength of the dipole distorts the symmetry of streamlines and shifts the zone of higher temperature gradient.

It was found that the magnetic field had a positive effect on heat transfer in low porous Rayleigh numbers and high Hartmann numbers; however, in high porosities and high Rayleigh numbers, the presence of the magnetic field decreased the heat transfer rate.

Summary: In this study, the pseudoplastic model is used to analyze the mass and energy transmission through a stretched permeable surface using trihybrid nanofluid. The influence of porosity is examined by employing the Darcy-Forchheimer relation in the momentum equation. The thermal efficiency of the nanocrystals is evaluated by integrating them with a pseudoplastic substrate. The findings show that the hybrid and trihybrid nanofluids have a greater tendency for fluid energy and velocity propagation rate compared to simple nanofluids, with an enhancement in velocity and heat transition rate.

Summary: The theoretical analysis of unsteady, squeezing nanofluid flow is studied in this research. By using the Navier Stokes Equation, Energy Equation, and Concentration Equation, the flow of nanofluid between two parallel plates in a rotating system is analyzed with variable physical properties such as viscosity and thermal conductivity. The study considers the effects of Thermophoresis and Brownian motion in the nanofluid model. The results show the relationship between parameters such as skin friction, Injection parameter, Squeezing number, Prandtle number, Schmidt number, and Rotation parameter, as well as their effects on the Velocity field, Temperature variation, and Concentration profile. The Parametric Continuation Method (PCM) is employed to obtain the results, which are further validated through BVP4c. The obtained results correspond to each other, indicating the accuracy of the analysis.

Summary: This research explores the steady laminar flow of nanofluid on a two-dimensional boundary layer using heat transfer of Casson across a linearly stretching sheet. The study examines the influence of Prandtl number, Brownian motion parameter, Lewis number, thermophoresis, and Casson fluid parameter on the nanoparticle concentration profiles, velocity, and temperature. The results show that the temperature increases as Nt and Nb increase, causing thickening of the thermal boundary layer. Additionally, it is observed that the temperature profile increases for higher values of the Brownian motion parameter, and the energy distribution grows with an increment in the values of the thermophoresis parameter.

Summary: Research on nanofluids has shown that hybrid nanofluids, particularly ternary nanofluids, significantly improve the thermal conductivity and heat transfer properties of base fluids. The type, size, and ratio of nanoparticles are important factors in determining the effectiveness of ternary nanofluids. Further study is needed to understand the effects of combining different types of nanoparticles, particle sizes, shapes, and base fluids in three-particle nanofluids.

Summary: This study investigates the flow and thermal characteristics of MHD Casson nanofluid in a square enclosure with non-uniform heat source using the Brinkman model. The impact of governing parameters on local Nusselt number, streamlines and isotherms is demonstrated, showing the increase in Raleigh number results in sharp temperature rise in the middle of the enclosure with steeper thermal distribution near the walls. High values of the Rayleigh number also highlight the effect of the magnetic field as a force of retardation.
