为探究近海风电阵列化开发过程中的群桩基础非线性水动力干扰问题
该文基于CFD方法建立波-流联合作用下群桩水动力数值分析模型
采用高精度分离涡(DES)方法对群桩绕流场开展数值模拟
通过频域分析法对不同波流参数(波幅、周期、流速)下桩柱的水动力频谱特性开展分析。结果表明:1)当流速、波浪周期固定时
谱峰频率、谱峰值随波幅增长呈非线性变化
且高幅值占比会随波幅增长逐渐增大;2)当流速、波幅固定时
波浪周期增大导致谱峰频率增大
且出现频率稳定的谱峰、次峰
谱峰值呈不规则变化
随着周期变化高幅值占比也随之变化;3)波参数的水质点速度在波流水质点速度中的相对比重
决定了桩柱波浪力的频谱特征。随着流速增大
相同波幅、周期工况下谱峰频率增大
在谱峰频率2倍处出现次峰;当流速减小时
次峰频率仅为谱峰频率的1.5倍。
In order to investigate the nonlinear hydrodynamic interference issues associated with multiple foundations during the development of offshore wind power arrays
this paper establishes a numerical analysis model for the hydrodynamics of OWTFs under wave-current action
utilizing the computational fluid dynamics (CFD) method. The high-precision detached-eddy simulation (DES) technique is employed to numerically simulate the flow field around OWTFs. Additionally
a frequency domain analysis method is applied to investigate the hydrodynamic spectral characteristics of OWTFs under varying wave-current parameters
including wave amplitude
period
and flow velocity. The results indicate the following: 1) When flow velocity and wave period are fixed
the spectral peak frequency and peak value exhibit nonlinear changes with increasing wave amplitude
and the proportion of high amplitude gradually rises with wave amplitude; 2) When flow velocity and wave amplitude are held constant
an increase in wave period leads to a rise in spectral peak frequency
with both spectral peak and sub-peak occurring at stable frequencies. The spectral peak value shows irregular fluctuations
and the proportion of high amplitude varies with changes in the period; 3) The spectral characteristics of the wave force on OWTFs is determined by the relative proportion of the water particle velocity of wave parameters in the water particle velocity of wave-current. As flow velocity increases
the frequency of the spectral peak rises under the same wave amplitude and period conditions
and a sub-peak emerges at twice the frequency of the spectral peak. Conversely
when flow velocity decreases
the sub-peak frequency is only 1.5 times that of the spectral peak frequency.
