摘　　要：基于CFD方法对三维数值波浪水池的双浮体波浪能转换装置进行时域模拟,将基于该方法得到的圆柱形浮体运动幅值与国内权威数据进行对比,验证了该CFD方法的准确性.计算了双浮体波浪能转换装置在特定波浪参数条件下的垂荡位移、垂荡速度和垂向受力,研究浮体底部构型的变化对双浮体式波浪能转换装置的水动力特性和运动响应的影响,并且从流场的角度分析浮体底部构型变化对波浪能转换装置的能量吸收与耗散的影响.计算结果表明,具有半球形状浮体的波浪能转换装置的运动性能最佳,而浮体构型的变化几乎不影响支撑立柱在垂荡运动中的能量吸收与耗散.研究结果可以为深水波浪能的工程应用提供理论基础,为后续振荡浮子波浪能发电装置优化提供依据.Time-domain simulation of dual buoy wave energy converter(WEC)in three-dimensional numerical wave tank is presented using the computational fluid dynamics(CFD)method.The accuracy of the CFD method is verified by comparing the heave displacement amplitudes of the cylindrical floats obtained from the simulation with authoritative data in China.We calculate the heave displacement,velocity,and vertical force of the WEC under specific wave conditions,investigate the effects of changes in the bottom configuration of the buoys on the hydrodynamic characteristics and motion response of the WEC,and analyze the impact of these changes on the energy absorption and dissipation of the WEC from a flow field perspective.The calculation results show that the WEC with semi-spherical buoys has the best motion performance,and changes in the buoy configuration have little effect on the energy absorption and dissipation of the support column during heave motion.The research results provide a theoretical basis for the engineering application of deep water wave energy utilization and provide a basis for optimizing oscillating buoy wave energy generation devices in the future.
