Sacrificial gold coating enhances transport of liquid metal in pressurized fountain pen lithography

open access: yesScientific Reports, 2021
Liquid metals have attracted attention as functional components for moldable electronics, such as soft flexible connectors, wires or conductive ink. The relatively high surface tension (> 400 mN m−1) and the fact that liquid metals do not readily wet ...

Numerical simulation of crystallization blocking in tunnel drainage pipes based on dynamic mesh and level set

open access: yesCarsologica Sinica, 2023
The complex hydrogeological conditions in karst areas lead to frequent water seepage and water gushing disasters in tunnels, which often require supporting drainage systems to prevent and control water hazards.

Water exchange and pollutant diffusion law in Gangnan reservoir

open access: yesAlexandria Engineering Journal, 2022
Gangnan Reservoir is an important water source of Shijiazhuang, the seat of northern China’s Hebei Province. The irregular shape of the reservoir makes it easy for water to stop flowing in bays, forming dead water areas.

Instability waves in a subsonic round jet detected using a near-field phased microphone array [PDF]

open access: yes, 2006
We propose a diagnostic technique to detect instability waves in a subsonic round jet using a phased microphone array. The detection algorithm is analogous to the beam-forming technique, which is typically used with a far-field microphone array to ...

Validating Semi-Analytic Models of High-Redshift Galaxy Formation using Radiation Hydrodynamical Simulations [PDF]

open access: yes, 2018
We use a cosmological hydrodynamic simulation calculated with Enzo and the semi-analytic galaxy formation model (SAM) GAMMA to address the chemical evolution of dwarf galaxies in the early universe.

Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]

open access: yes, 2006
A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...
