Summary: This study experimentally investigated the rheology and viscosity of nanofluids containing SWCNT, showing that the fluid index decreased and the consistency factor increased with increasing concentration of SWCNT. The viscosity of the nanofluids depended on the effective size of SWCNTs, and they exhibited viscoelastic properties due to the formation of a solid spatial lattice of nanotubes.

Summary: The purpose of this study is to analyze the viscosity and rheology of nanofluids containing single-walled and multi-walled carbon nanotubes and compare their findings. The experiments involved a variety of nanofluids with the same base fluids and weight concentrations of CNTs and surfactants. The results showed that nanofluids with single-walled carbon nanotubes exhibited significantly higher viscosity than those with multi-walled carbon nanotubes. Most of the studied nanofluids exhibited pseudo-plastic or viscoplastic behavior, despite the Newtonian nature of the base fluids. Correlations describing the rheology of all investigated nanofluids were provided, along with the observation that the viscosity of nanofluids increased with a decrease in the average hydrodynamic size of nanotubes. The microrheology of these nanofluids was also studied, revealing the dependence of their elastic modulus on the concentration of CNTs.

Summary: This study investigates the potential of composite allotrope boron nitride nanobarbs (BNNBs) as nanoparticles for enhancing the thermal conductivity of nanofluids based on mixtures of ethylene glycol and propylene glycol with water. BNNBs exhibit high thermal conductivity due to efficient phonon transfer and they are electrical insulators owing to their wide bandgap. The study showed that BNNBs enhanced the thermal conductivity of carrier fluids up to 45%, and the enhancement was proportional to the concentration of BNNBs. The findings suggest that BNNBs have great potential for use as thermally conductive nanoparticles in nanofluids for various heat transfer applications.

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 mathematically investigates the heat and mass transfer during the peristaltic flow of a non-Newtonian Jeffrey fluid inside an elliptic cross-section duct. The analysis considers constant heat absorption and provides a descriptive assessment of the heat and mass transfer. Exact solutions are obtained using a polynomial solution technique for the dimensionless partial differential equations in the problem. A purposeful graphical assessment is provided for the final mathematical results. Velocity and temperature profiles reach their highest values in the core region of the duct and gradually decrease towards the duct boundaries.

Summary: This article explores the influence of buoyancy on the magnetic Eyring-Powell nanofluid flow over a stretching surface. Coupled similarity equations are derived from the governing flow equations. Numerical computations are performed using the shooting method to solve the constitutive ordinary differential equations. The impacts of various fluid flow parameters, nano concentration parameters, and heat transfer are graphically illustrated for both aiding and opposing flows, revealing that skin friction is minimally affected by the buoyant force induced by temperature differences, and the rate of heat transfer increases for aiding flow while decreasing for opposing flow.

Summary: This study mathematically models the stagnation point flow over a heated stretching cylinder using the phase flow approach. The interaction between impinging stagnation flow and flow due to the stretching surface of the cylinder is thoroughly interpreted. Exact analytical solutions are computed and evaluated graphically. 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: The paper introduces new tubular shapes resulting from the imposition of Navier's velocity slip at the surface. A family of pipes induced by the slip mechanism is discovered, which modifies traditional pipes with elliptical cross-sections and resembles collapsible tubes. The velocity and temperature fields of the new pipes are analytically determined, and physical features such as wall shear stress and convective heat transfer are studied in detail. The new pipes are considered to have engineering and practical value in the micromachining industry.

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.

By using this transform, we solve higher-order linear differential equations and determine conditions for Hyers-Ulam stability. This study introduces the Tarig transform method to demonstrate the stability of both linear and nonlinear differential equations, particularly those with constant coefficients. Additionally, we examine various applications of the Tarig integral transform in linear, nonlinear, and fractional differential equations.

Summary: The purpose of this article is to investigate the influence of thermal stratification and medium porosity on the gravity-driven transport of hybrid carbon nanotubes on an upright extending sheet under the influence of a constant applied magnetic field, as well as the effects of thermal radiation, viscous dispersal, and joule heating. The mathematical interpretation of the governing flow problem is done using rectangular coordinates, and homothetic analysis is employed for simplification. The numerical investigation is carried out using the MATLAB software. The key findings of the study show that the presence of hybrid carbon nanotubes and medium porosity significantly increase the surface shear stress magnitude, while the external magnetic field and velocity slip effects are altered. This study may serve as a benchmark for the fueling process in space vehicles and space technology.

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.

Summary: This study numerically analyzes the heat transfer through a higher grade Forchheimer porous CuO-H2O-nano-medium in an unsteady MHD porous flow. The flow governing equations are solved using finite difference and finite element methods, and simulations are performed for various parameters of interest. The results show that the larger porosity of the nanomedium leads to larger skin friction, the plate's temperature increases with the Forchhiemer number, and the hydrodynamic velocities decrease as the porosity increases.
