Axial flow pumps possess a unique structure where there must be clearances between the impeller and piping wall, usually not exceeding 0.1% of diameter. Despite small size clearance, internal micro-vortex structures have non-negligible impact on main field impeller. Under action pressure difference suction surfaces blades, some fluids form high-energy jets in tip clearance area, known as leakage vortices (TLVs). TLV interacts with field, exerting significant state, energy loss, hydraulic...
Liquid jets impinging on surfaces are widely found in various industrial processes, such as spray painting, high-pressure water jets, and dishwashers. The liquid can break up into sprays with discrete, small-scale features that difficult to reveal. This work proposes a multiscale solver OpenFOAM achieves two-way conversion by capturing the large-scale interface using Volume of Fluid (VOF) approach tracing droplets Discrete Phase Model (DPM). By comparing VOF–DPM standard VOF solver,...
van der Waals layered structures, notably the transitional metal dichalcogenides (TMDs) and TMD-based heterostructures, have recently attracted immense interest due to their unique physical properties potential applications in electronics, optoelectronics, energy harvesting. Despite recent progress, it is still a challenge perform comprehensive characterizations of critical these including crystal chemical dynamics, interlayer coupling, using single characterization platform. In this study,...
Centrifugal pumps, which are essential for the transfer of fluids, extensively utilized in industries like aerospace and new energy vehicles. These fields require pumps to meet rigorous standards terms reliability, efficiency, vibrational noise while also imposing stringent restrictions on their size weight. Therefore, achieving optimal performance both efficiency reduction centrifugal limited space poses a considerable difficulty. This study investigates impact different volute area ratios...
Abstract Process valves are responsible for regulating and controlling the rate direction of flow in pipeline systems. The V-port ball valve is one kind process with a performance influenced by V-angle. In this article, DN50 taken as research object. This work therefore aims to investigate effect relationship between V-angle on internal properties via experiments numerical simulations. Results indicate that an increase either or opening causes large-pressure fluctuation near outlet, thus...

Abstract To enhance the interface bonding of polyimide (PI)/carbon fiber (CF) composites, CFs were functionalized by introducing a polydopamine (PDA) transition layer, whose active groups provide absorption sites for growth molybdenum disulfide (MoS 2 ) nanosheets and improve strength with PI. Uniform dense MoS thicknesses 30–40 nm on surface PDA@CF obtained via subsequent hydrothermal method. As result, between CF PI matrix becomes more compact help PDA layer nanosheets. This is beneficial...
Hazel leaf, a by-product of hazelnuts, is commonly used in traditional folk medicine Portugal, Sweden, Iran and other regions for properties such as vascular protection, anti-bleeding, anti-edema, anti-infection, pain relief. Based on our previous studies, the polyphenol extract from hazel leaf was identified quantified via HPLC fingerprint. The contents nine compounds including kaempferol, chlorogenic acid, myricetin, caffeic p-coumaric resveratrol, luteolin, gallic acid ellagic (ZP) were...
Hydrodynamic cavitation (HC) has emerged as a promising technology for water disinfection. Interestingly, when subjected to specific pressures, jet pump reactors (JPCRs) exhibit effective treatment capabilities. This study investigated the flow and vorticty transport in JPCR with various area ratios by utilizing computational fluid dynamics.

Valves are the key components used for flow control in process industry, and solid–liquid two-phase is commonly encountered during valve regulation. Solid particles impact wall surfaces cause continuous erosion, which undermines stability reliability of long-term operation. In this study, discrete element method (DEM) was to investigate flow-induced erosion characteristics inside a ball valve.
