Abstract

This paper studied the local scour processes at subsea structures using using the computational fluid dynamics codes (OPENSOURCE CODE). The model solved the fully three-dimensional, Reynolds-averaged Navier–Stokes equation closed with the LES model. Stokes and Cnoidal Waves were generated using Fenton’s Fourier series method. Two empirical models must be used to compute the boundary layer at the interface and bed-load transport. We used the types of structured Cartesian grids. The velocity amplification at the corners is the dominant flow mechanism that controls the maximum scour depth. The results were agreement with the experimental study.
