Single metal droplets are widely used in electronic packaging and flexible circuit printing. However, the high density and interfacial tension of liquid metals make it difficult for the jet to stably generate single metal droplets, which greatly rest...
The Brinkman equation provides a convenient continuum description of flow through digital cores containing resolved pores, unresolved porous voxels, and solids. Nevertheless, two issues are usually encountered in explicit solvers. The first is the in...
Ray-like swimmers achieve propulsion through undulatory pectoral-fin motions, but the hydrodynamic consequences of these prescribed motions remain incompletely understood. We investigated a bio-inspired ray model that combines geometry reconstructed...
As the core of the thermal management system in new energy vehicles, the operational reliability of electronic water pumps directly affects vehicle thermal safety. Radial force and pressure pulsation, as key indicators, significantly impact the opera...
In this study, we proposed and evaluated a new dielectrophoresis (DEP)-based device for the high-throughput, non-invasive separation of cells with similar physical properties. Although DEP is an established technology for separating biological partic...
How an airfoil generates lift is settled engineering practice—the Kutta–Joukovsky theorem relates lift to circulation, and the Kutta condition selects the observed flow—yet why the Kutta condition holds has again become a subject of...
Patient-specific computational fluid dynamics (CFD) is increasingly used to investigate intracranial aneurysm hemodynamics. However, differences in modeling practices can affect simulated flow fields and derived metrics, complicating interpretation a...
Resolving fluid flow structures with multiscale features or boundary layers that arise in many real-world applications effectively requires the use of spatially nonuniform meshes with localized clustering of grids. The lattice Boltzmann (LB) method,...
Force measurement is a fundamental diagnostic technique in experimental fluid mechanics. However, conventional instrumentation, such as mechanical balances and pressure taps, is often intrusive, geometry-dependent, and mechanically constrained. This...
Drag sensitivities quantify how changes in rheological parameters affect the force on a confined body. Continuous adjoints are implemented with finite volumes for creeping Carreau flow and low-Reynolds-number Oldroyd-B flow past cylinders. The Carrea...
The wind pressure coefficient
Phase-change transpiration cooling, in which a liquid coolant flows through a porous medium, absorbs heat, and undergoes phase change while forming a protective gas film, is widely regarded as one of the most efficient active thermal protection conce...
With the global energy transition and large-scale renewable integration, thermal power units are shifting from base-load to peak-shaving roles, but deep peak shaving may cause combustion instability and increased emissions. High-temperature solid-par...
We develop two parametric data-driven reduced models: a physics-informed neural network (PINN) and a non-intrusive tensorial reduced-order model (TROM), and apply both approaches to the parametrized one-dimensional shallow-water dam-break problem. Bo...
Cyclone separators are widely used for gas–solid separation; however, improving separation efficiency generally increases pressure drop, making cyclone design a challenging multi-objective optimization problem. This study aims to optimize a hig...
The breakup of confined fluid threads in a circular sudden contraction microchannel was investigated by combining high-speed imaging with three-dimensional simulations using the Volume of Fluid (VOF) method. The effects of the capillary number
The CFD study investigated three different groove geometries: circular, rectangular, and trapezoidal grooves, and these results were compared to a smooth tube. The results obtained from this CFD study were compared with experimental work completed fo...
Introduction: Ventricular pressure and arterial flow are commonly evaluated separately, although their instantaneous product represents hydraulic power. This study examined whether synchronized ventricular pressure and arterial flow recordings can be...
This study compares the hydraulic performance of two centrifugal-pump impellers operating in pump and pump-as-turbine (PAT) modes: a reverse-engineered impeller obtained from a commercial pump by 3D scanning and an impeller developed through a prelim...
Indirect dry cooling systems are key cooling equipment in water-scarce power plants, and their cooling performance is strongly affected by ambient temperature and crosswind. Reliable performance prediction under variable meteorological conditions is...
Sprinkler irrigation is an effective method to protect tea buds and leaves from frost injury. This study was conducted to investigate the freezing process of sprinkler irrigation water on leaves of tea cultivar “Zhongcha 108” under radiat...
The formation of internal patterns in drying protein droplets is commonly interpreted as a consequence of evaporation-driven hydrodynamic transport. Here, we show that the residence time of the HSA–NaCl system before the hygrometric transition...
Propellant feed systems for small liquid rocket engines are commonly modelled as hydraulic networks discharging into a prescribed chamber pressure. Such models cannot represent the feedback between delivered mass flow and chamber pressure, and theref...
A series of two-dimensional numerical simulations were performed by solving the Navier–Stokes equations to investigate the flow past a vertical plate in close proximity to a smooth wall at a fixed Reynolds number of Re = 150. The effects of the...
Tropical cyclones are among the most destructive weather systems, causing substantial societal and economic impacts worldwide. Accurate visualization and identification of tropical cyclone vortex structures are essential for understanding their organ...
