Simulating river flow velocity on global scale [PDF]
Advances in Geosciences, 2005 Flow velocity in rivers has a major impact on residence time of water and thus on high and low water as well as on water quality. For global scale hydrological modeling only very limited information is available for simulating flow velocity. Based on the

Journal of Marine Science and Engineering, 2022 WC-Cr3C2-Ni coatings are a vital class of hard ceramic/cermet coatings with potential applications as wear-resistant materials. However, their erosion wear behavior in 3.5 wt.% sodium chloride medium (SCM) remains largely unexplored.

Flow velocities of Alaskan glaciers [PDF]
Nature Communications, 2013 Our poor understanding of tidewater glacier dynamics remains the primary source of uncertainty in sea level rise projections. On the ice sheets, mass lost from tidewater calving exceeds the amount lost from surface melting. In Alaska, the magnitude of calving mass loss remains unconstrained, yet immense calving losses have been observed.

Modeling Bed Shear Stress Distribution in Rectangular Channels Using the Entropic Parameter
Entropy, 2020 The evaluation of bed shear stress distribution is fundamental to predicting the transport of sediments and pollutants in rivers and to designing successful stable open channels. Such distribution cannot be determined easily as it depends on the velocity

ASM Science Journal, 2021 Excessive sediment deposition results to hydro-ecological problems particularly for shallow streams that experience significant point-source pollution. In recent times, models have been employed to investigate sediment transport in river systems. The aim

Velocity inversion in nanochannel flow [PDF]
Physical Review E, 2007 The nanoscale cylindrical Couette flow is investigated by means of molecular dynamics simulations, in the case where the inner cylinder is rotating whereas the outer cylinder is at rest. We find that the tangential velocity of the low is inverted when the fluid-wall interaction near the outer cylinder is weak and the fluid density is low.

Influence factors of pressure loss in pipeline transportation of paste slurry
工程科学学报, 2015 A new pipe loop test platform was built to study the influence factors and levels of pressure loss in slurry pipe transportation. The influences of pipe inner-diameter, flow velocity, slurry concentration and particle size on the pressure loss were ...
