| 船舶阻力预报是反映船舶安全性与快速性的关键指标。针对现有阻力计算方法存在的耗时长、精确度不够等问题,提出一种利用FLUENT数值模拟技术来实现的拖网渔船阻力预报的快速优化法。船舶球艏对阻力性能具有非常大的影响,应用参数设计法生成一系列球艏的型线,实现模型的通用化表达,提高流场转换和分析的灵活度,解决经验设计中不可控变量所导致的偏差,经实验结果比较,验证该方法计算速度快、预报精度高,设计模型适用于工程和研究,具有较强的实用性和参考价值。 |

| It is important to predict the ship resistance in terms of security and fast of the ship. Aiming at solving the problem of present resistance calculation which is time-consuming and accuracy is not enough, this paper will apply the optimization method of resistance prediction on the bulbous bow for a stern trawler by FLUENT in numerical simulation technology. The bulbous bow has a big impact on resistance performance. In order to reduce errors caused by uncontrollable variables in experience design, using parametric design method which complete the universal expression of the models and increase the flexibility of flow field conversions and analyzes to change the form of a series of bulbous bows. After comparing the experimental results, showing the optimization method is fast and accuracy, the models for engineering and research is practical and having a reference value. |
