摘　　要：基于CFD方法,运用水动力计算软件STAR CCM+对一载液浮式生产储卸油船(FPSO)模型进行数值模拟,分析横浪状况下波浪频率、波幅、液舱装载率对FPSO液舱晃荡与船舶耦合运动的影响。结果表明:液舱晃荡对FPSO垂荡运动基本无影响,横摇运动的影响因波浪频率变化表现为增摇或者减摇;当波长接近船长时,载液率增加,船舶横摇幅值增大,波幅增大时,FPSO运动响应加剧,液舱晃荡对舱壁的砰击更加剧烈。Based on the CFD method,the hydrodynamic calculation software STARCCM + is used to numerically simulate a carrier liquid FPSO model,and the effects of wave frequency,wave amplitude and tank loading rate on the FPSO tank sloshing and the coupled motion of the ship are analyzed under the condition of transverse waves. The results show that the tank sloshing basically has no effect on the heave motion of the FPSO,and the influence of the rolling motion is manifested as increasing or decreasing rolling due to the wave frequency;when the wavelength is close to the length of the ship,the liquid carrying rate increases,and the rolling amplitude of the ship increases. When the wave amplitude increases,the motion response of the FPSO is intensified,and the slamming of the bulkhead by the tank sloshing is more severe.
