摘要
为探讨阻流板对船体水动力性能的影响,采用FLUENT软件对双体船安装阻流板前后的水动力性能进行了研究.通过对安装阻流板前后船体阻力、升力和纵倾力矩的计算对比,讨论了安装阻流板前后双体船水动力性能的变化.计算了带有不同高度阻流板的双体船在不同航速下的阻力、升力和纵倾力矩,比较了带有不同高度阻流板的双体船水在不同航速下的动力性能,并对安装阻流板前后尾部速度分布、尾流场波形及船体升力增加的区域进行了研究,探讨了阻流板改善船体水动力性能的作用.
The hydrodynamic performances of the catamaran with and without interceptor was investigated by software FLUENT to the effect of interceptors. The difference of the hydrodynamic performances of the catamaran with and without the interceptors was investigated by comparing the resistance, lift force, and trimming moment. The hydrodynamic performances of the catamaran with different height interceptors of different velocities were investigated by comparing the resistance, lift force, and trimming moment in different conditions, and the velocity distribution, wave form at the ship stern and the region of the ship surface, where the lift force increases were investigated. The function of the interceptor to improve the hydrodynamic performance was also discussed
