Abstract By using the CFD (Computational Fluid Dynamics) software, RNG (Renormalization Group) turbulence model and mud shield module are employed to establish a three-dimensional mathematical of scouring around wind power pile foundation. The reliability is verified by literature results. A new foundation protection method proposed. thickness diaphragm protective layer 0.5 cm, 1 2 4 6 8 10 cm....

Based on four years of spatially synchronous topographic data the Oujiang Estuary from 2002 to 2019, variations and physical mechanisms estuarine evolution driven by natural conditions human activities since beginning this century were analyzed. The results show that has changed dramatically in past 20 years. From net sediment erosion estuary was 163.44 million m3, average bed elevation river-d...

Abstract A computational fluid dynamics numerical model addressed the problem of local scouring and deposition calculation for non-cohesive sediment clear water conditions near single double cylindrical piers. The results piers correlate very well with physical model's while are higher than case pier, especially when large-eddy turbulence model, van Rijn bed-load transport equation, fine mesh s...

Mining activities can endanger the stability of hydraulic structures. Numerical modeling local scouring around hydrodynamic and circular bridge pile groups, due to action clear water conditions via non-cohesive sediment, was performed using a computational fluid dynamics (CFD) model, large eddy simulation (LES) turbulence van Rijn sedimentary model with FLOW-3D software. The groups were positio...
