| 摘 要： | 船艇水动力的计算方法目前主要有模型实验法、理论经验估算法和计算机模拟法.为了更好地预报船艇水动力性能,运用不同方法对2种典型船艇在不同漂角下运动时横向力进行计算,并对各自结果进行了对比分析,得出各种计算方法的优缺点.研究表明,流体计算软件(Fluent)精度较高,计算速度快,能解决人脑有时不能解决的问题.同时,Fluent计算软件为船艇水动力性能的预报等研究提供良好的方法和有益的探讨.

| Abstract: | At present the computational methods of hydrodynamic force of watercraft in maneuvering motion are mostly model experimentation,experience computation and computer simulation. In order to predict better and conveniently the hydrodynamic force performance of watercraft in maneuvering motion,the different methods are applied to calculate the orientation forces when the watercraft is sailing at different draft angles. Then computational results from each method being compared and analyzed,the ranks of the meth... |
