Abstract Traditional parallel straight microchannels are limited by low heat flux density and non-uniform flow distribution. From a system optimization perspective, incorporating surface grooves provides an effective means to enhance solid-liquid interaction and improve overall performance. Using water as the working fluid, this study numerically investigates the coupled effects of inlet flow rate, groove number, and groove spacing on the thermo-hydraulic behavior of groove-type microchannel heat sinks. The results reveal a fundamental trade-off between heat transfer enhancement and hydraulic resistance. Increasing coolant velocity significantly improves heat dissipation, but also raises the pressure drop, affecting pumping power… More >

Abstract Perforated partition walls are widely employed in complex underground transportation systems to mitigate tunnel pressure waves, harness train-induced piston wind for reduced ventilation energy consumption, and support emergency operations. Building on orifice flow theory, this study develops a one-dimensional flow model for tunnels equipped with perforated partition walls. The model is applied to examine the aerodynamic performance of such walls in extra-long tunnels through a comprehensive parametric analysis, considering the presence of openings, opening ratio, spacing, and spatial arrangement. The results demonstrate that, for opening ratios, defined as the ratio of the perimeter of a… More >

Abstract To investigate transient flow instabilities in parallel-channel regenerative cooling systems subjected to nonuniform heat flux, a three-dimensional transient numerical model was developed to couple variations in supercritical fluid thermophysical properties with endothermic pyrolysis kinetics. The spatiotemporal evolution of RP-3 fuel within parallel channels was analyzed, and the role of a midstream interconnection structure in mitigating flow maldistribution was clarified. During the initial heating stage, the viscosity reduction of the supercritical fuel produced a drag-reduction effect that temporarily maintained a nearly uniform flow distribution. As the wall temperature increased and the pseudocritical region approached, the sharp… More >

Abstract The effective management of gas–liquid two-phase flow, emerging within the microchannels of proton exchange membrane fuel cells (PEMFCs) during operations, is crucial for improving energy conversion efficiency. In this study, the influence of surface wettability is examined for hydrophilic and hydrophobic conditions through a visualization-based experimental setup focused on single-droplet dynamics. The impact of key parameters on droplet behavior is systematically explored, while the mechanisms underlying the observed flow patterns are elucidated and the coupling among governing physical factors is clarified. The results show that, under comparable conditions, hydrophobic surfaces exhibit larger advancing contact angles More >

Abstract Type 2 Diabetes mellitus is a disease that afflicts approximately 537 million individuals all over the world, and continuous glucose monitoring (CGM) systems have become very important in the management of the disease. Nonetheless, the existing centralized data architecture of CGM generates high privacy and security risks, as sensitive patient health data can be easily abused. This paper introduces an original structure that incorporates both federated learning and blockchain technology and allows for predicting glucose safely and preserving privacy without affecting the integrity of the data. Our model uses the Long Short-Term Memory (LSTM) neural… More >

Abstract Thermal-transfer printing technology has gained widespread adoption in small-format printing devices owing to its fast printing speed, good image quality, and environmental sustainability. However, scaling this technology to large-format printing equipment remains challenging, primarily because the internal heat transfer mechanisms in the large-scale thermal-transfer printing head (TPH) are not yet fully understood. This knowledge gap limits further optimization of device design. A two-dimensional model was established to numerically investigate the internal heat transfer within the thermal-transfer printing head under pulse heating conditions. The simulations reveal that the internal temperature distribution adopts a star-like pattern, driven More >

Abstract Subway operations generate substantial heat, and inadequate dissipation can progressively degrade tunnel thermal conditions. The thermal distribution within the surrounding rock is critical for calculating the load on subway environmental control systems. However, the heat transfer patterns in the surrounding rock for intersecting tunnels remain poorly understood. Therefore, this study employs COMSOL software to numerically analyze the impact of intersecting line layouts on the temperature field distribution within the surrounding rock. Results indicate that when tunnels intersect, heat accumulates in the surrounding rock near the intersection. Compared to the single-tunnel structure, intersecting tunnels exhibit higher… More >

Abstract Dynamic methods for creating a superheated state of liquids and tracking their decay are presented. These methods allow relaxation characteristics of short-lived metastable states to be investigated across a wide range of temperatures and pressures. The relaxation of a medium is studied by a “probe” action after a short “pump” pulse. The concentration of the pump pulse in time and space allows the synchronization and localization of means for recording fast-flowing processes. Our aim was to carry out a brief review of methods for studying pulsed thermal processes in a superheated liquid based on the… More >

Abstract Acer truncatum is a significant woody oil-bearing tree species known for its ability to synthesize various unsaturated fatty acids. This study systematically analyzes the lipid metabolic pathways and the associated transcript abundance changes involved in the biosynthesis and accumulation of seed oil in A. truncatum. By integrating lipidomics and transcriptomics analyses across different developmental stages of A. truncatum seeds, we thoroughly investigate the dynamic characteristics of oil metabolism. The results show that triacylglycerols (TAGs) become the dominating lipid class throughout seed development and that their amount increases greatly as the seeds mature, whereas diacylglycerols (DAGs) show a significantly… More >
