This numerical investigation shows the effect of Keulegan-Carpenter number on sediment transport in monopile foundations, suggesting optimal spacing to reduce scour.
Key Points
Higher Keulegan-Carpenter (KC) values intensified sediment transport around monopiles, indicating a complex relationship.
Results demonstrated a significant shift in scour depth behavior at KC ≈ 14, indicating critical flow conditions.
Grouped cylinders with narrow spacing reduced scour effects compared to wider spacing, highlighting design implications.
The validated CFD model showed strong alignment with experimental data, confirming its predictive capabilities.
