摘要
为研究波浪条件对漂浮式水平轴潮流能水轮机发电装置的载体平台与水轮机之间水动力性能的影响,应用计算流体力学(CFD)方法,利用STAR-CCM+软件的DFBI运动模块,设置多种波浪条件,计算载体平台和水平轴水轮机耦合作用,分析得出不同波浪条件对系统运动响应的影响规律。研究表明,波幅和波长对载体平台和水轮机的纵摇、纵荡、垂荡均有显著影响,且纵摇、纵荡、垂荡随波幅的增大而增大;波长1.5倍载体总长时平台纵摇幅度最大,此波长也是纵摇共振波长和同步垂荡波长。
In order to study the hydrodynamic performance effects between the carrier platform and the turbine of the floating horizontal axis tidal energy turbine generator under wave conditions,the computational fluid dynamics(CFD)method is applied,and the DFBI motion module of STAR-CCM+software is used to set various waves condition.The coupling effect between the carrier platform and the horizontal axis turbine is calculate,and the influence law of different wave conditions on the motion response of the system is obtained.The results show that the amplitude and wavelength have significant impacts on the pitch,heave and heave of the carrier platform and the turbine.The pitch,pitch and heave increase with the increase of the amplitude.When the wavelength is 1.5times the length of carrier,the pitch reaches maximum,and it is resonance wavelength and the synchronous heave wavelength.
