本文主要是以有限差分法所建立之二維數值計算模式,分析在造波板的運動下,黏性波浪受潛堤或浮式防波堤等影響下,波浪消散情形之反應分析。模式中亦考慮完全非線性(fully nonlinear)效應的影響,最後據以完整的實例分析,分析結構物的消波作用。
A time-independent finite difference method is used to study the nonlinear viscous waves passing through submerged and floating breakwaters. The fully nonlinear kinematic free surface conditions and dynamic conditions are considered in the analysis. The surface tension effect is expected to be small and is neglected in the study. The numerical scheme is firstly validated by reported numerical results. The numerical results are then reported for various dimensions (depth and length) of breakwaters. The effects of floating and submerged breakwaters on wave reductions are, then, concluded:
