摘　　要：基于Star-CCM+软件建立三维数值波浪水槽,研究圆筒振荡水柱(OWC)装置在不同C型挡板开口角度和波向条件下的水动力特性及波能俘获性能。结果表明:C型挡板可对OWC装置波能俘获产生一定的增强效果,当波浪为正向入射且挡板开口角度为180°时增效幅度最优,在当前挡板高度下最高可提升43.7%的波能俘获效率。当开口角度小于180°或波浪为斜向入射时,与最优增效幅度相比,C型挡板会阻碍一定的入射波浪能量进入气室,从而导致气室内部液面和压强振荡减弱,增效幅度降低,在某些条件下甚至会产生负面效果。Utilizing the Star-CCM+software,a three-dimensional numerical wave flume is established to investigate the influence of both C-type baffle opening angle and wave direction on the OWC's performance.The results show that the C-type baffle can significantly improve the wave energy capture efficiency of the OWC device.The optimal efficiency gain is achieved at an opening angle of 180°under normal wave conditions,with an increase of up to 43.7%compared to the unbaffled OWC.However,baffles can also impede wave energy entry into the chamber when opening angles are less than 180°or under oblique wave conditions.This leads to the water level and pressure oscillations within the chamber to weaken,diminishing efficiency gains and even potentially producing negative effects.
