Numerical modeling of local scour and forces for submarine pipeline under surface waves
TLDR
In this article, a two-dimensional numerical model is developed to predict local scour around submarine pipelines induced by the orbital fluid motion under surface water waves, instead of being simplified to oscillatory flow, the wave motion is modeled using a fully nonlinear wave model.About:
