| 摘 要： | 通过应用仿驼背鲸前缘突起来提高船用翼的水动力特性已是目前非常热门的话题,为验证前缘突起的高度和突起个数与升力的关系,选用哈尔滨工程大学船舶控制工程教育部工程研究中心在船模水池实验室所做的减摇鳍动态水动力性能实验用的标准NACA00154号矩形鳍为研究对象,对其前缘进行正弦波变形,建立数学模型,并应用普朗特升力线性理论和切比雪夫数值逼近法,得出了前缘突起个数对升力的影响不大而突起幅值对升力有显著的决定性作用的结论.

| Abstract: | High-lift fin stabilizer design was and remains a topic of considerable interest in sea keeping industry.Bumps of humpback whale are such credible morph that enables enhancement of hydrodynamics of stabilizer fin.In order to further promote the application of bumps on stabilizer fin,NO.4 NACA0015 used by TOW TANK test of Harbin Engineering University was chosen,proper amount of bumps shaped as sine wave were introduced to the leading edge of the fin stabilizer,on which mathematical model was built up and Pr... |
