Water exchange and pollutant diffusion law in Gangnan reservoir

Alexandria 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.

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

, 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 ...

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

, 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]

, 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.

Cellular Uptake Behaviors of Rigidity-Tunable Dendrimers

Pharmaceutics, 2018
Understanding of the interaction between cells and nanoparticles (NPs) is critical. Despite numerous attempts to understand the effect of several parameters of NPs on their cellular uptake behaviors, such as size, shape, surface chemistry, etc., limited ...

Experimental Study on the Thrust-Radial Composite Porous Bearings with Hydrodynamic Shape Forming (Experimental Research of the Effects and Lubrication Characteristics of Radial or Thrust-Radial Composite Porous Bearings with Hydrodynamic Shape Forming on the Annular or on the End Surface)

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2004
This study proposes the combination of some hydrodynamic pressure shapes formed on the end surface or on the annular surface of porous oil impregnated sintered bearing as a DC spindle motor's bearing system, and examines experimentally to optimize the hydrodynamic shape combination as thrust-radial composite bearing.

Feedback and Recycled Wind Accretion: Assembling the z=0 Galaxy Mass Function [PDF]

, 2010
We analyse cosmological hydrodynamic simulations that include observationally-constrained prescriptions for galactic outflows. If these simulated winds accurately represent winds in the real Universe, then material previously ejected in winds provides ...

Hull Form Design Optimisation for Improved Efficiency and Hydrodynamic Performance of ‘Ship-Shaped’ Offshore Vessels

International Conference on Computer Applications in Shipbuilding 2015, 2015
'Eco-friendly shipping’ and fuel efficiency are important issues and challenges faced by marine and offshore industry today. This is primary due to increasing stringent environmental regulations and the pressure to reduce fuel cost to stay competitive. Furthermore, the technical requirements of offshore vessels have also increased significantly. Recent
