Summary: The study depicted the system dynamics of a planar slider-crank mechanism with multiple clearance joints using correlation dimension and bifurcation actions, investigating the effects of clearance size and driving speed on the bifurcations of the dynamic response and identifying the fractal dimension of the strange attractor. The controlled factors in the evaluation of correlation dimension were cautiously determined using the Cao method, Mutual Information function, and Grassberger-Procaccia algorithm. The compound effect of translational and revolute clearance joints on the mechanism dynamics was featured, showing that the correlation dimension of the slider displacement approximately saturates beyond a specific translational clearance value.

Summary: This paper presents two types of new deployable mechanisms based on the motion characteristics of the four-bar slider-crank mechanism (FBSCM): the prism mechanism with constant cross-section and the round deployable mechanism. A new basic planar deployable unit based on the path-generating characteristics of the FBSCM is proposed. The method of building a deployable mast unit with one DOF from the new planar deployable mechanism is given. The prism mechanism with constant cross-section of one DOF is constructed, and the magnification ratio is analyzed. Moreover, the deployable unit with a negative Poisson's ratio for building the round deployable mechanism based on the properties of functional output of the FBSCM is proposed. The structure of the round deployable mechanism is described, and the parameter model with multilevel deployment is calculated and validated with cases given; the DOF of the round deployable mechanism is one. Last, the static analysis of the round deployable mechanism is studied by simulation; by locking 6 guide rails, the structure is found to have a balanced bearing capacity, and the bearing performance is improved compared with locking only one guide rail.

Summary: The turbulent flow of nanomaterial (a mixture of CNT and water) within a circular tube of a solar system absorber was numerically simulated in this article. The tube was equipped with a complex swirl flow device to enhance fluid-wall interaction and achieve warmer fluid. Ten mirrors were used to concentrate solar radiation, and the geometric parameters were calculated to optimize optical performance. The simulation employed a K-epsilon model based on the finite volume method. The results showed that increasing the CNT fraction improved thermal performance, and changing the pitch ratio and flow rate had significant effects on friction factor and convective factor.

Summary: To address the challenge of thermal performance and heat loss in energy conversion systems, this study simulated a trapezoidal cavity with a wavy top wall containing water/ethylene glycol GO-Al2O3 nanofluid using the Galerkin finite element method. The effects of physical parameters, such as porosity, thermal radiation, magnetic field angle, Rayleigh number, and Hartmann number, on thermal performance and fluid flow were investigated. The optimized values for these parameters were determined to be 1214.46, 2.86, 0.63, 0.24, and 59.35, respectively. By applying RSM and Taguchi integration, the highest average Nusselt number of 3.07 was achieved, indicating improved thermal performance.

Summary: This article investigates the use of cross-shaped fins and different forms and volume fractions of Copper(II) oxide nanoparticles to improve the thermal efficiency of paraffin phase change materials (PCMs). Increasing the volume ratio of nanoparticles and shape coefficient can shorten the solidification time, while increasing the length of cross-shaped fins enhances the solidification rate and heat transfer. It was found that when the inner and outer walls are involved in the solidification process simultaneously, the solidification rate increases by more than 66%.

Summary: A scientific definition for laminar boundary layer flow and heat transfer of an incompressible viscous flow over a stretching cylinder near the suction/injection area is provided in this study. The study uses numerical and analytical methods to convert the differential equations into dimensionless coupled equations. The analysis shows that the suction process increases surface firmness and quality, while the injection process decreases surface skin friction. The use of water fluid accelerates the heat transfer process from the surface to the outside of the boundary layer.

Summary: This study evaluates the heat transfer phenomena of a nanofluid stream through a microchannel heat sink under the influence of a magnetic field. Aluminum oxide-water nanofluid is used as the cooling fluid, and the Koo-Kleinstreuer model is applied to calculate the viscosity and thermal conductivity of the nanofluid. The porous medium is modeled using the improved Darcy relationship, and the dispersion type of the two-equation approach is used to simulate heat transfer between the solid and fluid zones. The results indicate that the magnetic field has a direct impact on the Nusselt number, and heat transfer increases with the concentration of the nanofluid, with the highest heat transfer achieved at a concentration of 0.04.

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.
