准确估算作用在船体上的水动力是评价船舶操纵性的基础。船舶研究所开发的Navier-Stokes程序NEPTUNE已被推广应用于计算有/本文简要介绍了数值计算方法，并将计算结果与实验值进行了比较。水动力和尾流场的模拟结果与测量结果吻合较好，证明了本方法的实用性。
Accurate estimation of hydrodynamic forces acting on a ship hull is essential for the evaluation of ship maneuverability.In the present paper, the Navier-Stokes code NEPTUNE developed at Ship Research Institute has been extended to compute flows around a ship with/without a rudder in a maneuvering motion.Brief description of the numerical method is given followed by the comparisons of the computational results with experimental values.Since both the hydrodynamic forces and the wake flow fields show good agreement between the simulations and the measurements, the practical usefulness of the present method has been demonstrated.
