Liquid sloshing in tanks is a very complex nonlinear free surface fluid flow problem, which must be considered in most of the marine engineering problems such as naval architecture, offshore engineering and so on. Violent liquid sloshing in large containers can damage the tank structure due to the direct liquid impacting action. Sloshing also affects the capsizing process of the liquid cargo ship. Some works on mitigating sloshing by using all kinds of the baffles were thus followed with interests. Oil layers with thinner thickness were shown to reduce the sloshing load of water in tanks. The sloshing characteristics in tanks with different sizes were different, therefore, scaling effect of sloshing should also be considered. Sloshing in a tank can also be used as tuned liquid dampers (TLDs) to dampen wind, wave and flow-induced motions of floating or fixed marine platforms. This paper present an overview on recent advances of liquid sloshing hydrodynamics including sloshing mitigation by using anti-sloshing baffle, layered fluids sloshing, scaling effect of sloshing and TLDs.

储罐内液体晃荡是一个非常复杂的非线性自由表面流体流动问题，在船舶建筑、海洋工程等大多数海洋工程问题中都必须考虑这一问题。由于直接的液体冲击作用，大型容器中的剧烈液体晃动会损坏罐体结构。晃动也会影响液货船的倾覆过程。因此，一些使用各种挡板减轻晃动的工作引起了人们的兴趣。较薄的油层被证明可以减少水箱中水的晃动载荷。不同尺寸的罐体晃荡特性不同，因此还应考虑晃荡的结垢效应。坦克中的晃动也可以用作调谐液体阻尼器 (TLD) 来抑制风，浮动或固定海上平台的波浪和流动引起的运动。本文概述了液体晃动流体动力学的最新进展，包括使用防晃动挡板减轻晃动、分层流体晃动、晃动的结垢效应和 TLD。
