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....

In this article, current research findings of local scour at offshore windfarm monopile foundations are presented. The mechanisms and depth prediction formulas under different hydrodynamic conditions summarized, including the current-only condition, wave-only combined wave-current complex dynamic condition. Furthermore, article analyzes influencing factors on basis classical equations for predi...

Accurately predicting scour is important for its prevention around the foundations of offshore wind turbines. Many studies on local piles have been conducted. Chen et al. (2022) conducted analysis using largescale experiments and examined maximum depth. However, relationship between depth time has not yet investigated. Furthermore, only a few comprehensively scale effects similarity laws. In th...

Many permanent spillway tunnels of high earth-rock dams are rebuilt from their diversion tunnels. Scour problem is focused because of their high water head and velocity. Energy Approach is a new method to Estimating Scour and is used here to estimate the depth of scour downstream of 1 spillway tunnel of Zipingpu Project. The method is illustrated working fine by comparing its results with data ...
