摘要/Abstract

摘要： 运用OpenFOAM对完整和破损船舶在静水中进行自由横摇衰减运动的数值模拟，分析得到船舶的线性和非线性横摇阻尼系数.从初始横摇角、舭龙骨附体、破损形式以及破损过程等多个角度对横摇阻尼进行细致的比较和讨论，揭示了破损船舶的横摇阻尼特性.同时开展破损模型试验以验证数值方法的可靠性.在破损船舶的横摇运动数值模拟中，建立了第二类及第三类破损模型，成功处理了内外水耦合及内外水相通的复杂流体流动问题，为破损船舶的横摇运动和倾覆研究奠定了基础，并为破损船舶的稳性衡准制定提供了技术参考.

Abstract: Based on OpenFOAM, the linear and nonlinear roll damping coefficients of the intact and damaged ship are obtained through the simulation of ship free roll decay motion in calm water. The detailed comparison and discussion of various perspectives such as initial roll angle, bilge keel, damage forms and damage process reveal the characteristics of damaged ship roll damping. And then the damaged model tests are carried out to verify the reliability of numerical method. For numerical simulation, the second and the third forms of damage models are built. Both the damage process and the coupled problems of inside/outside fluid are successfully resolved. These studies lay a foundation for roll motion and capsize research of damaged ship, and also provide technical reference for study of damaged ship stability criteria.

Key words: roll damping, OpenFOAM, damaged ship, coupled motion
