Study on the Mechanism of Local Scour Around Bridge Piers

Journal of Marine Science and Engineering
Local scour around bridge piers poses significant challenges to the stability and safety of bridge structures. Local scour results from the combined effects of increased longitudinal flow velocity, the direct impact of the flow in front of the pier, and ...

Local Scour Mechanism of Offshore Wind Power Pile Foundation Based on CFD-DEM

Journal of Marine Science and Engineering, 2022
The local scour around offshore pile foundations often seriously affects the normal operation of offshore wind power. The most widely used numerical simulation method in the study of local scour is the Euler two-fluid model (TFM).

Visualization of the Onset of Scour under a Pipeline in Waves

Applied Sciences, 2020
This paper visualizes the onset of scour under a pipeline in regular waves and studies the mechanism in this process. After the test started, the sand particles near the downstream mudline began to oscillate periodically, probably due to the distribution
