SCALE EFFECT IN LOCAL SCOUR AROUND AN OFFSHORE PILE. (2023). Coastal Engineering Proceedings, 37, structures.88. https://doi.org/10.9753/icce.v37.structures.88
Abstract
Accurately predicting scour is important for its prevention around the foundations of offshore wind turbines. Many studies on local scour around piles have been conducted. Chen et al. (2022) conducted scour analysis using largescale experiments and examined the maximum scour depth. However, the relationship between scour depth and time has not yet been investigated. Furthermore, only a few studies have comprehensively examined the scale effects and similarity laws. In this study, experiments for analyzing local scour around a pile were conducted at different scales, 1/13, 1/65, and 1/130, to verify the scale effects and corresponding similarity laws regarding scouring time.References
