Numerical Modeling of Scour Development Around a Monopile Foundation Using Computational Fluid Dynamics

A key concern for offshore wind foundations (OWFs) is the development of scour around the
foundation, particularly in terms of the maximum scour hole depth and extension and its temporal
development. The aim of this study is to analyze the scour development around monopiles using
REEF3D::CFD numerical model. In this research, the foundation is subjected exclusively to
current loads to predict the maximum scour depth and its temporal evolution as well as the
extension of the scour hole. Experimental data from a previous study was used to validate the
numerical model. The numerical model showed a strong ability to capture the scour development
around the monopile when compared to experimental results.
