浮式防波堤拖航阻力性能研究

Study on the towing resistance performance of the floating breakwater

以特殊结构形式的防波堤力为研究对象,对其进行了拖航阻力的数值模拟和试验研究.首先对单个带锥头防波堤和不带锥头的防波堤进行了拖曳试验,试验结果表明：带锥头的防波堤的静水阻力比不带锥头防波堤的要减少58%-60%.其次通过对数值模拟结果与试验数据的比较,验证了数值模拟方法的可行性.最后,对组合后的防波堤进行拖航阻力试验和理论估算,并比较分析其结果.

Based on the complex structure of the floating breakwater,through numerical simulation and experiment study,it is shown that the breakwater with a conical head can have better drag-reduction effects. Firstly,by means of experiment on breakwaters with conical head and without conical head,the drag-reduction effect of the breakwater with a conical is reduced by 58% - 60%. Results are compared with test data from the towing test,showing that CFD technology can play an important role in the research. Finally,resistance experiment and theoretical calculation are carried out on the breakwater group,and the results are compared and analyzed.
