基于非静压单相流模型NHWAVE,设计不同的计算工况,系统研究了规则波与非规则波作用下,非淹没刚性植物的消波特性。将计算结果和实验数据进行对比分析,验证了非静压模型NHWAVE计算植物消波特性的准确性。进一步研究了波高、周期和水深等因素对植物消波特性的影响,探讨了植物消波特性与这些水动力因素的内在联系。结果表明:非淹没刚性植物的消波效率受波高和周期的影响较大,水深对消波效率的影响很小。由于波浪非线性的影响,基于线性波理论的消波理论模型对植物消波能力的估计偏小。

Based on the nonhydrostatic model NHWAVE, wave attenuation efficiency of non-submerged rigid vegetation subjected to regular and irregular waves was numerically investigated by designing different computational conditions. The computational reliability of NHWAVE in predicting wave attenuation of non-submerged rigid vegetation was well validated by comparing its predictions with the corresponding measurements. The effects of prominent factors, such as wave height, wave period, and water depth, on the wave attenuation efficiency of non-submerged rigid vegetation were also numerically investigate...
