Summary: The present study investigates the flow of liquid-holding nano-sized particles over a stretching surface. Copper particles are added into water as base liquid. The influence of micro rotation phenomenon is also considered. Non-linear coupled ordinary differential equations are obtained and solved numerically using the Runge-Kutta-Fehlberg scheme and shooting method. The effects of micropolar coupling parameter, microelements concentration, and nanoparticles volume fraction on velocity, temperature, and micro-rotation profiles are examined. Heat flux and shear stress are also computed and presented through bar graphs. The results show that material constant has increasing effects on normal components of flow velocity, but decreasingly influences tangential velocity, micro-rotation components, and temperature profile. An increase of 3.74% in heat flux is observed when the volume fraction of nanoparticles is increased from 1 to 5%.

Summary: The hexagonal Z-type ferrite Sr3Co2Fe24O41 (SrZ) was synthesised in 2001 and reported as a room temperature multiferroic material in 2010. Its high frequency and microwave properties, as well as ferromagnetic resonance frequency (FMR), have been less investigated. This study measured the complex permeability and permittivity of a single phase polycrystalline ceramic sample of SrZ in the X-band frequency range and found a strong FMR at 2.3 GHz, which could be tuned by an external magnetic field. This discovery has significant implications for creating a tuneable microwave filter or absorber.

Summary: This study successfully synthesized soft ferromagnetic spinel MFe2O4 (M = Ni, Mg, Zn) nanoparticles using Citrus limon fruit extract as fuel via microwave-assisted combustion synthesis. The introduction of desired divalent metal ions led to the formation of phase pure polycrystalline NiFe2O4, MgFe2O4, and ZnFe2O4 nanoparticles. VSM analysis revealed different saturation magnetization values for the MFe2O4 nanoparticles, which are strongly correlated with the magnetic moment of divalent cations, superexchange of Fe3+ ions, particle size/morphology, and impurities.

Summary: This study considers the physical model of time-dependent, laminar, and incompressible flow of two-dimensional hybrid nanofluids inside two co-axial stretchable disks. The velocity components (u, w) are dependent on the radial distance r and the normal direction z. The continuity, momentum, and energy equations are solved using the finite element technique. The results show that increasing the magnetic parameter reduces the velocity near the disks, while increasing the shape factor Ns decreases the thermal conductivity HDnf. The shear stress and heat transfer rate decrease with parameters a, f(1), f(2), but increase with parameters M, Re, and Ns.

Summary: This investigation focuses on explaining the heat transfer and entropy generation of Magnetohydrodynamics (MHD) viscous fluid flowing through a ciliated tube. Heat transfer study is of great significance in various biomedical and biological industry problems. The metachronal wave propagation is identified as the main cause of the viscous creeping flow. A low Reynolds number is employed to account for the weaker inertial forces and to satisfy the creeping flow limitations. A large wavelength of the metachronal wave is considered for the cilia movement. Entropy generation is used to analyze the heat transfer through the flow. Numerical solutions are obtained using MATHEMATICA, and exact mathematical solutions are calculated and analyzed with graphs. Streamlines are also plotted, revealing an axially symmetric flow and temperature profile. Both velocity and temperature profiles reach their maximum values in the center of the ciliated tube and decrease towards the boundaries.

Summary: This article presents a comparative study of magnetohydrodynamics stagnant point flow in hybrid nanofluid using the extended versions of the Yamada-Ota model and Xue model. The study considers a time-dependent and thermally radiative two-dimensional flow with a stretchable/shrinking permeable sheet. The hybrid nanofluid is formulated by suspending Aluminum Oxide Al2O3 and Copper Cu nanoparticles in water. The nonlinear dimensionless system of ordinary differential equations is solved numerically using the bvp4c methodology. The study finds that the heat transfer rate is higher in the Yamada-Ota model compared to the Xue model, and increasing the stretching parameter enhances the velocity field but deteriorates the temperature distribution.

Summary: This study developed a thermal insulation composite material using buffing dust-laden tanning waste mixed with polystyrene and a blowing agent, aiming to promote resource recovery and a circular economy. The composite material exhibited good thermal conductivity, compression strength, density, and water absorption compared to conventional insulation panels. The addition of buffing dust reduced the thermal conductivity of polystyrene by 10%. The composite material also showed thermal stability and the presence of functional groups. Overall, this work not only solved energy consumption issues but also contributed to environmental protection and air pollution reduction through recycling and reusing buffing dust waste as thermal insulation material.

Summary: In this study, the slip velocity of a non-Newtonian nanofluid flowing above a stretching surface with double-diffusion effects is examined. The initial partial differential equations are transformed into dimensionless form, and comparison variables are introduced to reduce them into ordinary differential equations. The reduced ordinary differential equations are then solved numerically using the shooting method. A comprehensive parametric study is conducted to investigate the effects of different parameters on the velocity, temperature, salt concentration distribution, local Nusselt number, and Sherwood number in both assisting and opposing flow cases.

Heat transport analysis and Nusselt number interpretation are incorporated. The results show a dominant impinging stagnation flow for higher oncoming flow pressure and lower stretching velocity of the cylinder.

Summary: This paper presents a comprehensive study on the mathematical modelling and numerical simulation of non-Newtonian blood flow in an idealized stenosed artery. The results show that the non-Newtonian nature of the fluid model significantly influences flow dynamics, with a greater degree of stenosis leading to higher velocity and pressure drop. Wall shear is substantially larger in stenotic passages, and the severity of stenosis is directly related to this increasing behavior.

Summary: This study investigates the influence of hybrid nano-fluid on heat transport in a semi-annular channel using numerical methods. The hybrid nano-fluid consists of a liquid water with a suspension of SWCNT and MWCNT. Constant heat fluxes are applied to the channel walls. The finite volume approach is used to solve the governing equations. The results show that heat transport decreases as the volume fraction of MWCNT increases. The heat transfer from the walls to the fluid is affected by the curvature of the walls. The study provides velocity contours, isotherms, and local Nusselt number distributions for certain volume fractions of nanoparticles. It is discovered that walls with smaller curvature have stronger convection heat transfer. The pressure increases with the increase of nanoparticle volume percentage.

Summary: This article investigates the modeling and numerical simulation of Magnetohydrodynamic (MHD) buoyancy driven convection flow in a differentially heated, square enclosure. Numerical solutions are computed for different values of Rayleigh number ranging 103 < Ra < 107 and Hartmann number ranging 0 < Ha < 40. Comportment of MHD free convection heat flow from transient to steady state is numerically examined for a period of 0 to 1 s. It is seen that with increasing values of Rayleigh number there is increase in local Nusselt number distribution on heated side of the cavity, while velocity distribution in the flow domain decreases with increasing Hartmann number.
