摘要
采用FLUENT软件对一模型艇在不同漂角下运动的升沉力系数和表面压力分布进行计算,验证了该软件解决此类问题的有效性。在此基础上,对作操纵运动的潜艇主体和带附体的全艇体,在一定攻角和漂角下的垂向力、俯仰力矩和横向力、纵倾力矩进行计算,取得了工程上较为满意、实用的精度,为解决潜艇操纵运动水动力预报的困难做出了有益的探索。
The FLUENT software is used to calculate the eoefficient of heaving force and surface pressure distribution when the submarine is sailing at different draft angle. The comparison of the numerical results with that of experiments and some theoretical ones proves the validity of FLUENT to solve this kind of problem. Then, the hydrodynamic loadings, including heaving force and pitch moment, are calculated for the main body of submarine with or without appendages under certain angle of attack. The is practical to numerically predict the hydrodynamic loadings of the submarine in maneuvering motion.
