Summary: The main objective of this study is to investigate the heat and mass transfer in an Ag-H2O thin film flowing past a stretching sheet with thermal and velocity slips. Various variables including porosity, thermal radiation, thermophoresis, and Brownian motion are taken into account, and the impact of nanoparticle volume fraction is analyzed using a modified Buongiorno model. The results show that an increase in the mixed convection parameter enhances the temperature profile and reduces the velocity profile, while thermophoresis increases both temperature and concentration profiles. Moreover, higher volume fractions of nanoparticles lead to higher temperatures and lower velocities.

Summary: The research aims to control fluid flow in a vertical microtube by creating a pressure gradient through heat transfer analysis. The motion of the membrane generates pressure, regulated by buoyancy forces. Wall deformation and membrane kinematics result in fluid movement. Analytical solutions were derived using dimensional analysis and lubrication technique, and simulations were conducted using MATLAB software. The impact of parameters on various flow properties and variables was visually demonstrated. Results showed that the volumetric flow rate increased with Debye length progression, while it had the opposite effect with Helmholtz-Smoluchowski. Streamlines did not vary significantly during contraction but showed extreme contour outlines during expansion in Helmholtz-Smoluchowski.

Summary: This article presents a novel design of a vortex chamber with axial grooves for cooling the leading edge of turbine blades. The chamber generates a vortex through nine tangential inlets and includes an axial groove. The grooves enhance flow turbulence and increase heat transfer by disrupting the thermal boundary layer. Using a 3D model based on the Reynolds-averaged Navier-Stokes equation, different turbulent models and experimental data were compared, with the Reynolds stress model (RSM) showing the highest accuracy. Various groove sizes, positions, and numbers were examined to study the vortex structure and heat transfer mechanism. The results revealed improved heat transfer in the chamber with grooves, especially with three grooves resulting in an average Nusselt number increase of over 4%. The pressure difference between chambers with and without grooves was not significant, but the highest friction factor occurred in the case with three grooves.

Summary: The influence of porous media on the solidification of water with hybrid nanoparticles has been simulated in this study. A tree-shaped fin and the impact of radiation were utilized to expedite the process. The hybrid nanomaterial consisted of a mixture of Al2O3 and CuO with a volume fraction of 0.01 for each powder type, making the homogeneous mixture approximation logical. A wiremesh packed approach was used to model the porous foam, and the impact of porosity on the freezing process was analyzed. The temperature equation, including two source terms for radiation and phase changing, was considered, and the Galerkin method was implemented for solving the equations.

Summary: Arterio-venous grafts (AVGs) are commonly used for long-term vascular access in hemodialysis. Intimal hyperplasia (IH) caused by unfavorable hemodynamic conditions is the main reason for AVG failure. This study utilizes computational fluid dynamics (CFD) to assess the impact of different geometrical designs on the hemodynamic conditions at the venous anastomosis. The results show that optimizing the anastomosis angle and introducing cross-sectional ridges in the graft can significantly reduce the risk of IH development.

Summary: In this study, the authors investigated the performance of a shell and helically coiled finned tube heat exchanger using numerical and experimental methods. They examined the heat exchanger with simple annular fins for the first time and proposed four new fin geometries, selecting the stepped fin geometry as the superior design. The authors developed correlations to predict the mean Nusselt number on both the shell and tube sides, with good accuracy (maximum 10% error) for calculating the Nusselt numbers. The results showed that the mean Nusselt number of the coil side was consistent across all geometries, and the Reynolds number had little effect on the mean Nusselt number on the other side.

Summary: The MHD extended flow of second-grade viscoelastic nanofluid on a curve stretching surface in two-dimensional mode is investigated, considering factors such as Joule heating and curvature parameter to examine the heat and mass transfer rates. Nonlinear ordinary differential system is obtained through appropriate transformations, and the quasi-linearization method is used for numerical solutions. The influence of specific variables on the fluid properties is studied. It is concluded that increasing the Schmidt number prevents the growth of fluid concentration, while temperature increases due to an increment in radiation parameter. The viscous fluid velocity and concentration decrease faster compared to the viscoelastic fluid. The surface drag force is an increasing function of the non-Newtonian fluid. Increasing the values of Nt and Nb leads to a higher heat transfer rate for the second-grade fluid compared to the Newtonian fluid. The mass transfer of the second-grade fluid is significantly affected by the Schmidt number and chemical reaction parameters compared to the Newtonian fluid.

Summary: Regarding the thermal management of the storage unit, one possible solution is to use an extended surface made of highly conductive metallic materials. This study suggests four different arrangements of the system by changing the number and thickness of plates, and solid matrix made of Silicon Carbide, Aluminum, and Stainless Steel. Additionally, loading alumina nanoparticles improves the heat absorption of the phase change material. Increasing the number of radial plates and reducing their thickness enhances heating penetration. The best case in terms of melting speed is achieved when using 40 plates with a thickness of 0.5 mm made of SiC material, resulting in a 87.84% reduction in melting time compared to the worst case.

Two methods, visual and inductive, are used to measure the frequency of bubble departure. The results show that the bubble departure frequency can decrease with increasing magnetic field strength and increase with increasing temperature of the heat-emitting surface. A linear stability analysis is conducted to analyze the influence of the magnetic field on the frequency of bubble formation during ferrofluid boiling.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
