带胸墙斜坡堤越浪量的数值试验研究
|
摘要
采用黏性流体的连续性方程、雷诺时均N-S方程作为基本控制方程,RNG k-ε模型模拟湍流效应,VOF方法捕捉流体自由表面,结合主动吸收式造波理论,借助FLUENT软件建立二维不规则波数值水槽。在验证数值水槽造波性能的基础上,数值模拟带胸墙斜坡堤的越浪,并将数值计算的平均越浪量与已有物模试验值进行对比,两者趋势一致,吻合良好;表明该数值水槽模拟不规则波作用带胸墙斜坡堤越浪的准确性。针对带胸墙斜坡堤,藉此分析了堤顶超高、斜坡坡比、坡肩宽度及坡肩高度对其平均越浪量影响的规律性,研究成果对斜坡堤工程设计具有重要的参考意义。
On the basis of the continuity equation and Reynolds averaged N-S equations of viscous fluid,RNG k-ε and VOF method,A 2 D irregular wave numerical wave flume which can eliminate the secondary reflection wave was built by using active absorbing wave theory and FLUENT software. After testing the efficiency of the numerical wave flume,the flume was used to simulate the overtopping of sloping breakwater with crown-wall. The comparation between the results of numerical and physical simulation shows the efficiency and accurency of the numerical model to simulate the overtopping. Then the influence of some factors on the overtopping of sloping breakwater with crown-wall was analysized. The research findings can provide reference for the engineering design.
