摘要
为研究导流板对波浪作用下海底管线的影响,在FLUENT中建立二维数值波浪水槽对不同导流板高度的海底管线附近波浪场进行数值模拟,并将计算结果与试验结果进行了比较,结果表明,计算结果与试验结果较为吻合。添加导流板后管线表面压力分布及波浪力均发生变化。水平波浪力最大值随着导流板高度的增大而增大,而垂直波浪力最大值则随之逐渐减小。
In order to study the submarine pipeline with spoiler under wave action,a two-dimensional numerical wave flume is established based on the FLUENT package.The wave field around pipeline with different sizes of spoiler was simulated and the numerical results were compared with experimental results.The comparisons show that the present numerical model works well.The spoiler changes the pressure distributions along the pipeline surface and hence the wave forces.In addition,the maximum horizontal wave force increases with the height of spoiler while the maximum vertical wave force decreases.
