| 摘 要： | 以船舶操纵水动力预报为研究背景,通过对商用计算流体力学软件FLUENT的二次开发,采用其动网格技术以及后处理系统,对大型船舶操纵水动力导数进行了数值计算.船体按照斜航、不同舵角、纯横荡和纯首摇等状态做运动,得出随船坐标系下作用于其上的水动力及力矩.通过进行基于最小二乘法的曲线拟合,最终求得船舶操纵水动力导数.计算结果与势流理论计算结果一致,表明了所提出的计算方法适用于复杂船舶运动的水动力导数计算.

| Abstract: | In order to predict the ship maneuverability in viscous flows,hydrodynamic derivatives related to ship maneuvering were analyzed using a dynamic mesh method and post-processing system,which was based on the commercial software FLUENT. Ship maneuvering motions of the different heading angles,rudder angles,swaying and yawing are considered. Hydrodynamic forces and moments acting on a maneuvering ship are obtained in the body-fixed coordinate system. Thus hydrodynamic derivatives of the ship maneuvering motion... |
