摘要

针对扰流板型海上风电单桩基础冲刷防护结构

在已开展的扰流板尺寸及数量对冲刷防护效果影响的研究基础上

进一步探究来流攻角对冲刷防护效果的影响。在实际工程中

海流的流动方向是不确定的。为此

基于数值模拟的研究手段

通过改变扰流板的安装角来模拟不同来流攻角

以0°和22.5°攻角下扰流肋数量为8的扰流板和0°和30°攻角下扰流肋数量为6的扰流板结构为研究对象

对其冲刷防护特性进行研究。分析扰流板结构在不同来流下马蹄涡强度和位置的变化特征

以及床面剪切应力的分布和相对保护面积的变化规律。研究发现

冲刷防护效果基本随着来流攻角的增加而减弱

且随扰流板长度或高度的增加

其角度变化带来的保护面积的差异也逐渐增加。总的来说

来流攻角为0°具有较好的冲刷防护效果。

Abstract

Based on the research conducted on the influence of spoiler dimensions and quantities on scour protection effectiveness for offshore wind turbine monopile foundations

this study further investigates the impact of flow incidence angle on scour protection effectiveness. In practical engineering

the direction of seawater flow is highly variable. Therefore

this paper adopts numerical simulation methods to simulate different flow incidence angles by changing the installation angle of the spoiler. The study focuses on two spoiler structures: one with 8 ribs tested at 0° and 22.5° incidence angles

and another with 6 ribs tested at 0° and 30° incidence angles. The scour protection characteristics of these structures are analyzed. The study examines how the intensity and position of the horseshoe vortex change under different flow conditions

as well as the distribution of bed shear stress and variations in relative protected area. The research findings indicate that scour protection effectiveness generally decreases with increasing flow incidence angle. Additionally

as the length or height of the spoiler increases

the differences in protected area increase with increasing angle variations. Overall

a flow incidence angle of 0° provides better scour protection effectiveness.
