摘要
浮式防波堤能够为海洋工程装备提供有效防护,满足海上设施日益增长的防护需求。使用计算流体动力学方法对带翼板浮式防波堤消浪性能进行数值模拟,分析翼板参数对防波堤消浪效果和涡量分布的影响。研究结果表明,当翼板角度过大时翼板尖端产生的漩涡强度变小,防波堤的消浪性能降低;当波高较大时,翼板角度减小使得漩涡脱落时间延长,从而提升其消浪性能;翼板长度较短会加速漩涡脱落,导致其消浪性能减弱。
Floating breakwaters can provide effective protection for marine engineering equipment and meet the increasing protection needs of offshore facilities.Computational fluid dynamics method is used to numerically simulate the wave dissipation performance of floating breakwater with wing plates,and the influence of wing plate parameters on wave dissipation effect and vortex distribution of the breakwater is analyzed.The research results show that when the angle of the wing plate is too large the strength of the vortex generated at the tip of the wing plate becomes smaller,and the wave dissipation performance of the breakwater is reduced.When the wave height is large,the reduction of the wing plate angle makes the vortex shedding time longer,thus improving its wave dissipation performance.The shorter length of the wing plate accelerates the shedding of vortex,resulting in the reduction of its wave dissipation performance.
