The advances in the research on coastal disasters, coastal ecological environments, waves and currents, coastal sediments and morphological changes, and coastal structures in japan are introduced by summarizing the papers which were presented in the annual conference on coastal engineering in japan
摘要介紹了日本第52回海岸工學講演會的概況,從海岸災害、海岸生態環境、波浪與水流、海岸泥沙運動與地形變化、海岸建築物等5個方面綜述了日本海岸工程研究的進展情況。It shows that after being improved the vof method can be selected to further study the interaction between surface waves and sandbars on the seabed
表明vof方法經過進一步的改進與完善,可成為深入研究波浪與不同海底沙壩地形之間相互作用的有效方法。In this paper, the physical experiment and numerical simulation based on the volume of fluid ( vof ) method to solve turbulent governing equations in the numerical wave tank are conducted to investigate the interaction between surface waves and sandbars on the seabed
本論文通過物理模型試驗和基於vof方法求解湍流控制方程所建立的數值波浪水槽模型,對波浪與海底沙壩地形之間的相互作用進行了研究。The physical experiments give the series of wave records under the interaction between surface waves and sandbars on the seabed. based on the series of wave records, reflection coefficients are calculat ed by goda ' s method and the bragg resonance are obtained
對物理模型試驗得到的波浪與正弦沙壩地形相互作用的波面序列,用goda的兩點法計算出反射系數,較好地反映出了bragg共振現象。In the physical experiments, two incident wave heights, fifteen wave periods and four different boundaries on the end of the wave tank are selected for both plain and sinusoidal sandbar topography
物理模型試驗中,選取了2個入射波高、 15個波浪周期和四種水槽末端邊界條件,分別設置了平底和正弦沙壩地形。In the numerical simulation, the open boundary and 1 : 1 slope on the end of the wave tank are considered with the other conditions same as the physical experiment ; the interaction between surface waves and the triangle / trapezium sandbars on the seabed is also studied
數值模擬中,除了對水槽末端為開邊界及1 : 1斜坡、其餘條件與物理模型試驗相同的情形進行了研究之外,也對波浪與三角形和梯形沙壩地形的相互作用進行了研究。The numerical model based on vof method gives the bragg resonance phenomena and the resonant reflection coefficient agrees well with the result of physical experiment. the numerical simulation on the interaction between surface waves and the triangle / trapezium sandbars on the seabed also shows the bragg resonance and the resonant period matches the davies " prediction
應用vof方法所建立的數學模型,在與物理模型試驗相同條件下,數值模擬反映出的bragg共振現象及得到的最大反射系數與物理模型試驗結果吻合;對波浪與三角形或梯形沙壩地形相互作用的數值模擬也較好地反映出了bragg共振現象,共振周期與davies理論預測一致。分享友人
