横摇阻尼系数是船舶耐波性预报中的一个重要参数，横摇阻尼试验是计算横摇阻尼系数的重要手段。而由于海军舰船（球首方尾）外形的复杂性，对其横摇阻尼运动的数值模拟还很少见。基于CFD方法对DTMB 5512模型在不同初始横摇角下的横摇阻尼运动进行了数值模拟，并根据模拟结果计算了船舶的横摇阻尼系数，计算结果与实船试验数据吻合较好。© 2010由爱思唯尔有限公司出版。由资源、环境和工程学会负责选择和/或同行评审
Roll damping test is used to calculate roll damping coefficient, which is an important coefficient in predicting ship seakeeping capability. And because of the complexity of naval ship’s shape (with bulbous bow and transom stern), it’s rare to find the numerical simulation of its roll damping motion. In this paper, DTMB5512 model’s roll damping motions at different initial roll angles are simulated based on CFD, vessel’s roll damping coefficients are calculated through the simulation results, and the results show good agreements with the tank test data. © 2010 Published by Elsevier Ltd.
