摘要：

摘要：应用非均质多相流模型对不同装载率和激励频率下矩形液舱的横摇晃荡运动进行了数值模拟.分析了液体重心的横向和纵向运动情况，计算了不同工况下自由液面形状与速度场分布以及舱壁测点处压力的时间历程和相应的功率谱密度.模拟结果与均质模型计算结果和试验结果的对比分析验证了非均质模型在模拟液舱晃荡时的优越性.

Abstract:

Abstract： Three rollinduced sloshing cases involving two filling levels and two excitation frequencies are simulated by using the inhomogeneous multiphase model. The lateral and vertical movements of liquid gravity center are analyzed. The free surface profiles, velocity amplitude distribution, the time history of impact pressures and corresponding power spectrums are calculated by the presented approach. The excellent capability of the multiphase model for sloshing simulation is validated by the qualitative and quantitative comparisons of experimental and numerical results obtained by inhomogeneous and homogeneous multiphase models, respectively.

Key words: liquid cargo ship, sloshing, numerical simulation, inhomogeneous flow, multiphase model
