摘要
船舶液舱晃荡是一种常见的流体运动现象,通常发生在部分充满液体的液舱中,诸多工程实际应用往往会涉及到液体晃荡问题;当液舱与船体运动发生耦合,将使船体运动加剧甚至倾覆,运用Fluent6.3模拟了液舱在不同内部结构下的液舱晃荡抑制效果,提出了晃荡在激励下的变化规律以及抑制晃荡的改进措施。
As a common phenomenon in liquid motions,sloshing usually happens in a partially-filled liquid tank of moving ship. Liquid sloshing is associated with various engineering problems.When coupling with ship motions,liquid tank can cause violent motions and even capsize under extreme conditions.Based on Fluent6.3,the effects on restraining the liquid tank sloshing are simulated.The different trends of sloshing under excitation and the improving methods for restraining sloshing are pointed out.
