摘要
大型试验水池反射干扰的消除效果是提升波浪质量、真实模拟海洋环境的关键。文中介绍了一种针对大型试验水池的新型复合被动消波器,该消波器采用网状结构、水平板以及三角消波网等复合形式。针对新型复合被动消波器,在大型造波水池内设计了验证试验,采用两点法分析了消波效果。结果表明:该新型试验水池被动消波器消波效果良好,消波反射率均小于15%,最小可达2%,波高差异对消波器的消波效果影响不显著,短周期波浪的消波效果优于长周期波浪。
Eliminating reflection interference in large test pools is essential for improving wave quality and accurately simulating ocean environments.This study introduces a new type of composite passive wave absorber designed for large wave tanks,incorporating a combined structure of mesh,horizontal plate,and triangular wave-absorbing network.A validation experiment was conducted in a large wave-generating pool,and the wave dissipation performance was evaluated using the two-point method.The main findings are as follows:the new composite passive wave absorber exhibits excellent wave dissipation performance,with reflection coefficients below 15%and a minimum as low as 2%.Wave height variation has no significant effect on the absorber’s performance,while its effectiveness is greater for shorter-period waves than for longer-period waves.
