摘　　要：以15万总吨级大型邮轮为研究对象,分别开展迎浪工况下航速6 kn时的波浪增阻模型试验和基于三维势流理论的数值计算,并根据试验和计算的结果预报实船波浪增阻和总阻力。结果显示:模型试验和数值计算得到的波浪增阻因子响应函数及波浪增阻的变化趋势一致,在考虑风阻力后由模型试验与数值计算预报的实船总阻力之间的最大相对误差为3.6%。采用数值计算方法进行大型邮轮安全返港波浪增阻预报是可行的。The design and evaluation of a safe return to port(SRtP)system is one of the key technologies in the development of a large cruise ship.Regulations require that,after a single propeller fails,the remaining propulsion system should be capable of propelling the ship at the speed of no less than 6 knots under sea conditions with Beaufort force 8 level winds,where the wave-added resistance is an important component in the total hull resistance.A large cruise ship with nearly 150,000 gross tonnages is selected and tank model tests for the wave-added resistance are conducted under the speed of 6 knots and head sea condition,and numerical calculations based on the 3D potential flow theory at the same condition are carried out as well.Comparison of the numerical calculation with the model test shows that their trends of the wave-added resistance and the RAO of the sample ship are consistent,and the difference in the total resistance is not more than 3.6% after windadded resistance is taken into account.It is verified that the numerical calculation method is acceptable to predict wave-added resistance for large cruise ships under SRtP conditions.
