A NEW NUMERICAL WAVE FLUME COMBINING THE 0-1 TYPE BEM
融合0-1类型边界元法的数值波算法
Introduction
Interactions between waves and maritime structures are an important issue in ocean and coastal Engineering. The development of efficient and accurate numerical models is an important way to study the wave-structure interactions and the Boundary Element Method (BEM) and the Volume Of Fluid (VOF) method are widely used in the numerical simulation of the interactions between waves and structures.
简介
波和海上结构之间的相互作用在海洋及海岸工程的一个重要问题。发展高效和精确的数值模型是研究波结构的相互作用和边界元法(BEM)的重要途径和流体体积(VOF)方法被广泛应用于波浪与结构物相互作用的数值模拟。
Many non-linear wave models, established by using the BEM, can deal with both arbitrary incident waves and complex bottom topographies . Sun et al. established a numerical wave model by the 0-1 type BEM. In the model, the constant element method is used for the normal derivatives of the wave potential function, and the value of the function at the geometric center of any element is adopted for the value of the element.
许多非线性波模型,利用边界元法建立的,可以处理任意的入射波和复杂的海底地形。Sun等。通过建立0-1型边界元数值波浪模型。在该模型中,常量元素的方法用于波势函数的正常衍生物,并在任何元素的几何中心的功能价值是通过元素的值。
Meanwhile, the linear element method is used for the wave potential function. The VOF method is an efficient way to simulate the intense motion of waves, such as turbulence, sloshing, breaking and wave-structure interactions. Zhao carried out numerical simulations of the extreme wave generation by using the VOF method. Li et al. established a numerical model based on the VOF method to investigate the regular waves interacting with a submerged horizontal twin-plate breakwater.
同时,线性元方法用于波势函数。VOF方法模拟波的激烈运动的一个有效途径,如湍流,晃动,破碎和波结构的相互作用。赵的极端波的产生进行了数值模拟,利用VOF方法。Li et al.。建立了一个基于VOF方法的数值模型研究与浸没水平双板防波堤的波浪的相互作用。
Though the BEM has prominent features of high accuracy and fast calculation speed, difficulties will arise when it is used to simulate intense wave motions as the BEM is based on th e potential flow theory. Meanwhile, the VOF method is very suitable to capture the real-time free surface of fluid and thus can be used to describe the wave breaking and the water particle turbulence well, but this method requires a huge numerical resource in solving the N-S equations. Furthermore, the VOF models suffer from the numerical dissipation over a long distance of propagation. Hence, to simulate the wave and structure interactions efficiently and accurately, a new model should be established.
Based on this idea and considering the merits of the both methods mentioned above, a new numerical
coupling model is established in this paper. In this model, the wave transformation in front of structures
is calculated by the 0-1 type BEM, and the intense wave motions near the structures are calculated by the
VOF method. This paper will be arranged as follows. The basic equations and boundary conditions are dis-
cussed in Section 1. The comparison between the BEM and the VOF method is presented in Section 2.
The coupling treatments of the new model are described in Section 3. The verification of 本论文由英语论文网提供整理,提供论文代写,英语论文代写,代写论文,代写英语论文,代写留学生论文,代写英文论文,留学生论文代写相关核心关键词搜索。
