| 摘 要： | 升力数值的大小直接影响零航速下船舶减摇效果。为产生足够升力实现船舶在零航速下的有效减摇,提出了基于变形鳍的零航速减摇鳍设计方法。基于势流理论和旋涡作用力理论对变鳍型减摇鳍在零航速下升力进行分析,给出了升力解析表达式。通过计算流体力学软件Fluent对变鳍型减摇鳍进行升力数值计算。最后将Fluent计算结果与解析表达式结果对比,升力值基本吻合,验证了该种升力分析方法的正确性,为零航速下减摇鳍的设计提供了理论支持。

| Abstract: | The numerical value of lift has a great effect on performance of ship anti-roll.In order to get a good impact of ship anti-roll,transmutative fin is introduced into zero-speed fin stabilizer system firstly.The lift on transmutative fin is analyzed based on potential theory and vortex counterforce theory and the lift model is set up based on the analysis.Computing the lift of transmutative fin at zero speed with Fluent.That lift from computing and academic has a great homology validates.The veracity of lift ... |
