摘要
基于CFD技术建立的数值波浪水槽试验,使用了波浪理论构建的数值水槽模型,在一定程度上能够代替物理实验的波浪水槽。数值波浪水槽构建难点在于实际波浪由于受到建筑物、地形等影响,往往会发生破碎、涡旋等现象,造波消波方法的选择也会对数值水槽建立和计算的准确性产生不同程度的影响。本文采用FLOW-3D软件,利用VOF方法,建立波浪数值水槽,将实验结果与Vincent and Briggs的椭圆浅滩实验结果对比,二者较为一致,说明波浪数值水槽结果合理有效。
The numerical wave flume experiment based on CFD technology and the numerical flume model constructed by wave theory can replace the wave flume in physical experiments to some extent.However,broken wave and vortex phenomena are major difficulties of numerical wave flume construction due to the influence of actual topography and buildings.In addition,the selection of wave generation and wave absorption might also have varying degrees of impact on the establishment of numerical flume and the accuracy of calculations.In this paper,the numerical wave flume is established by using FLOW-3D software based on VOF method.After being compared with Elliptical shoal experiment by Vincent and Briggs,we found the results are consistent to each other.It shows that the numerical wave flume is reasonable and effective.
