波浪中的船舶操纵涉及到船舶阻力、耐波、推进和操纵等方面，是一个复杂的、多因素相互影响的船舶水动力学问题。虽然传统的船舶操纵运动研究方法已经较为成熟，但考虑船桨舵相互作用下的复杂波浪环境中船舶操纵运动具有多时空尺度流动耦合、多级物体运动控制、大分离流动等特点，目前尚无可靠的全耦合研究方法，也缺乏精确化的全耦合数值分析工具。本项目将构建基于分离涡模拟方法和自航船舶操纵运动控制的精确化求解模型，开发波浪中船舶操纵运动一体化全耦合直接求解方法。通过动态重叠网格技术处理船桨舵复杂运动，基于区域造波技术实现移动计算域中的波浪场生成，进而完成自航船舶在波浪中操纵运动的直接数值模拟，精确预报波浪中船舶操纵运动特性，分析波浪对船舶操纵运动的影响机理。通过数值模拟研究，建立示范性的标准算例和数据库，为波浪中船舶操纵运动的研究提供可靠的对比参考数据和有效的分析研究手段。

Ship maneuvering in waves includes the performance of ship resistance, seakeeping, propulsion, maneuverability and so on. It is a complex hydrodynamic problem with the interaction of many factors. Despite the fact that the traditional research method of ship maneuverability is mature, the free running ship maneuver in rough sea environment is characterized by multiple temporal or spatial scale flow, motion control with hull-propeller-rudder multilevel system and large flow separation, etc. So far, there is no reliable fully coupled method yet and an accurate numerical analysis tool is also absent. In this project, detached eddy simulation (DES) and maneuvering control module is developed to accurately solve the flow field and the ship motion. In addition, a fully coupled model for ship seakeeping, propulsion and maneuverability is established. Dynamic overset grid method is applied to handle the complex ship hull-propeller-rudder motion system; a relaxation zone technique is used to generate desired waves in moving computational domain. Direct CFD simulations of free running ship maneuver in waves are conducted to accurately predict the hydrodynamic performance. Based on the numerical simulations, benchmark cases and data are established to provide valuable information and a reliable analysis tool for the research of ship maneuverability in waves.
