摘要
基于格子Boltzmann法研究了波浪在潜堤上的破碎情况。通过建立数值波浪水槽,采用推板造波,模拟波浪与潜堤的相互作用,计算结果与实验数据进行对比,吻合良好,验证了该模型能较好地模拟波浪的破碎和传播。由于潜堤的阻碍和波浪破碎,沿程波高呈衰减趋势。在相同波高条件下,低水位反射系数随周期增大而增大,高水位反射系数随周期增大先增大后减小。
Wave breaking over a submerged breakwater is simulated based on Lattice Boltzmann Method.By establishing a numerical wave flume and using a push plate to make waves,the interaction between waves and submerged breakwater is simulated.The calculated results are in good agreement with the experimental data,and verify that the model can well simulate the breaking and propagation of waves.It is proved that the wave height shows an attenuation trend due to the obstruction of the submerged breakwater and the breaking of the waves.Under the same wave height condition,with the increasing of wave period,the reflection coefficient increases first and then decreases while it only increases at the low water level.
