Summary: The flow of electro-hydrodynamic (EHD) ferrofluid through a porous square shaped enclosure in the presence of constant heat flux is simulated, and the effects of enhancing medium permeability and electric field strength on the flow are analyzed through contour plots. The results show that increasing the medium permeability reduces the fluidity of the ferrofluid, and the temperature change is opposite with increasing permeability in the presence of an external electric field. Increasing the medium porosity makes the ferrofluid flow more regular.

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.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.
