在此基礎上進而分析了波浪對可滲透圓柱群的相互作用,推導出了作用於直線排列的群柱中單一柱體上的波浪力的近似解。In this paper, based on summarizing previous numerical studies on wave transformations, several works are documented : based on the mass conservation equation and euler ' s equation, the extended form of boussinesq equations is derived by using the velocity at an arbitrary water depth as the independent variable, and several terms are added into governing equations to model the effects of bottom friction, wave breaking and subgrid turbulent mixing
本文在總結概述前人關于boussinesq方程波浪數學模型研究進展的基礎上,主要做了以下幾點工作:從質量守恆方程和euler方程出發,以某一水層處水平速度矢量作為獨立變量,推導出包含底摩擦耗能、波浪破碎效應和子網格湍流效應的改進型boussinesq方程。In the end, in view of the fact that boussinesq - type equations and the mild slope equations are deduced from different hypothesis conditions and behave differently in simulation of wave propagation, the numerical results of wave propagation effected by strong non - linearity are given by the nonlinear three - dimensional mathematical model which was established for the calculation of 3 - d wave particle velocity and wave pressure and suitable to small size waters of arbitrarily varying depth
最後,鑒于boussinesq型方程和緩坡方程是在不同的假設條件下推導而來,應用於描述近岸水域波浪的傳播變形時具有不同的特點。本報告根據作者所建立的可以對任意水深點流場與波動凈壓力場進行求解、適宜水深任意變化水域非線性波傳播的數學模型,提供了在較強非線性作用下波浪傳播的數值模擬結果。The expression of the improved boussinesq equations in curvilinear orthogonal coordinate system is derived. on the basis of poission equation conversion, the methods to generate curvilinear orthogonal grids are introduced, and then the two - dimensional numerical wave model under curvilinear orthogonal coordinate system is established
推導了正交曲線坐標系下的改進型boussinesq方程,以poission方程變換為基礎,建立擬合正交曲線坐標系下正交曲線網格的生成方法,進而建立正交曲線坐標系下的二維波浪模型,提高了模型對復雜地形的適用性。Current. in order to make diffluent piers with low ridge to be popularized and applied, the surface wave of low fr. current is chosen as the research object. we measure the surface wave elements and the velocity distribution of various diffluent piers scheme by the experiment of physical model. we also analyze the average wave height, the the average value of the square of wave, unit width of the wave ' s energy, the probability density distribution of wave height, and the power chart character, so as to reveal the weakening wave mechanism of the diffluent piers
低fr水流的核心是波浪問題,為了低坎分流墩的推廣應用,本研究以低fr水流的表面波浪作為研究對象,通過物理模型試驗,對各種分流墩方案消能工的下游水面波浪要素、流速分佈進行測試,分析低坎分流墩下游波浪的平均波高、均方根、單寬波能、波高概率密度分佈及功率譜特性變化規律,從而揭示了低坎分流墩的削波機理。分享友人
