基于PIV技术不同形式防波堤周围涡旋场特性研究

摘要

The flow field around the submerged breakwater has complex turbulent change; and breakwater is more prone to the damage. By the PIV technique, and based on the model test, the research about velocity flow field and eddy characteristics of submerged breakwater under the action of regular waves has been carried out, and the velocity distribution of flow field can be obtained. By analyzing the experimental data under different hydraulic conditions of different breakwaters, the vortex field characteristics around breakwaters are quantitatively studied.%深水防波堤周围流场存在复杂的紊动变化，防波堤较容易发生失效破坏。本文利用 PIV 技术，基于模型实验，对规则波作用下防波堤周围的速度流场及其涡流特性进行了实验研究，获得了规则波流场的瞬时速度分布。通过对不同型式防波堤在不同的水力条件下的波浪流场实验数据的分析，定量地研究了防波堤堤身水域的涡旋流场的水力特性。
