计及纵倾影响的金枪鱼围网船最优阻力数值研究
|
摘要
针对金枪鱼围网渔船高航速的特点,采用CFD数值模拟方法对某型金枪鱼围网渔船正浮状态下不同航速的阻力进行数值预报确定合理速度;针对该速度分别考虑不同纵倾角度对航行阻力的影响,通过数值计算和对比发现适当纵倾可以明显减少该船型的航行阻力。本文研究结果在该类型船舶设计和运营中减小阻力及降低功耗提供有益参考。
In this paper, CFD numerical simulation method was used to predict the resistance of a tuna seine fishing boat to determine the reasonable speed. Then the influence of different trim angles on the resis-tance was considered. The results of numerical calculation showed that the ship's resistance could be obviously reduced with proper trim. The results of this study provided useful reference for reducing the resistance and reducing power consumption in the design and operation of this type of ship.
