| 摘 要： | 弧板式透空堤是由弧型板组成的新型防波堤结构。为探讨其透射系数的影响因素,利用Fluent软件基于N-S方程构建了波浪与板式透空堤相互作用的数值模型,讨论了相对潜深、入射波周期、相对波高、相对板宽和结构型式对透射系数的影响。结果表明:弧板式透空堤的透射系数随着相对波高和入射波周期的增大而增大,在静水面附近透射系数最小,尤以静水面和略高于静水面时的消浪效果最佳;在相同波浪要素条件下,静水面及其上0.02 m和0.04 m位置处,弧板式透空堤的消浪效果明显优于平板式透空堤。

| Abstract: | An arc-plate type open breakwater is a new type breakwater consisting of arc plates. To explore the influence factors of the transmission coefficient, a numerical model of the interactions between wave and plate type open breakwater based on the Navier-Stokes(N-S) equations with the help of Fluent is developed to analyze the effects of submergence, wave period, relative wave height, relative width and structure type on the transmission coefficient. Research results show that the transmission coefficient of the arc-plate type open breakwater increases with the increase of relative wave height and wave period. At the same time, the transmission coefficient is the smallest when the open breakwater is located at the still water surface. The effect of the wave attenuation performance is very significant when the open breakwater is located at the still water surface and a little more above the still water surface. For the same cases, the wave attenuation performance of the arc-plate type open breakwater is better than that of the horizontal plate open breakwater when the open breakwater is located at the still water surface, 0.02m and 0.04m above the still water surface. The research results have some guiding significance for the coastal protection of weak tidal regions. |
