Analysis of Restraining Sloshing in Liquid Tanks with Different Inner Structure Based on Fluent

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.
