摘 要：Many studies have been undertaken to predict local scour around offshore high-rise structure foundations(HRSFs),which have been used in constructing the Donghai Wind Farm in ***,there have been few works on the turbulent flow that drives the scour *** this study,the characteristics of the turbulent flow fields around an HRSF were investigated using the particle image velocimetry *** mean flow,vorticity,and turbulence intensity were analyzed in *** relationship between the flow feature and scour development around an HRSF was *** results showed that the flow velocity increased to its maximum value near the third row of the pile *** shear layer and wake vortices could not be fully developed downstream of the last row of the piles at small Reynolds *** strong flow and turbulent fluctuation near the third piles explained the existence of a longtail scour pattern starting from the HRSF shoulders and a trapezoidal deposition region directly downstream of *** laboratory experiment gains insight into the mechanism of the turbulent flow around HRSFs and provides a rare dataset for numerical model verifications.
