不同型线结构船艏表面压力特性对比实验研究

Comparison of surface pressure characteristics of bulbous bows in different profiles through wind tunnel tests

为优选船艏结构型线方案,在风洞中针对三个在结构型线上仅有细微差别的船艏方案进行表面压力特性对比测试。实验获得了各型线方案模型表面压力空间分布特性和压力脉动特性,并通过表面压力特性的综合对比进行了结构型线评估,为船艏的结构型线设计提供直接的技术依据。

To optimize the profile for a bulbous bow, experimental measurements were performed with 3 slightly different bulbous bow cases in a low speed wind tunnel. The spatial distributions of surface pressure as well as pressure fluctuations were obtained, and assessments on the bulbous bow cases were made in terms of surface pressure characteristics. The results of this study provided a technical support for the design of the bulbous bow profile directly.
