摘要:
为分析液舱流体晃荡对波浪中船体运动性能的影响,针对船体外流场与液舱内流场(液体非线性晃荡)分别采用时域势流理论方法计算,建立了在波浪中船体与液舱流体晃荡耦合的时域运动方程.其中波浪中船体水动力和时延函数采用切片法和脉冲响应函数法计算获得,舱内液体非线性晃荡采用时域边界元法计算.对S175加载方形液舱在迎浪横浪等不同工况下液舱流体晃荡及其与船体运动耦合分别进行了计算模拟与验证研究.研究表明,在不出现液面破碎等强非线性现象时,能够给出较好的液舱流体晃荡波形和压力;耦合运动模拟结果能清晰地反映液舱晃荡对船体运动的影响,并准确给出船体有无加载液舱时共振频率的偏移现象;数值与试验结果吻合良好,并具有较高的计算效率,为设计载液船舶或减摇水舱等的前期设计提供了快速有效的分析方法和技术手段.
