A numerical model containing density stratified layers of liquid oil and water in a rectangular tank is modeled to interact with a rigid porous structure in the form of a T-shaped baffle under sloshing conditions. The arbitrary Lagrangian-Eulerian method is used to track the evolution of the interfacial and free surface wave, with the Navier Stokes and Brinkman's equations governing the incompressible fluid flow and the flow through the porous region respectively. A series of setup cases are simulated with interest in observing the interaction of the layered fluid and the interfacial wave with a porous structure. The effect of the porous structure and its efficacy in damping associated sloshing waves and impact pressure on the tank walls is analyzed under various setup configurations.

对包含矩形油箱中液体和水的密度分层层的数值模型进行建模，使其在晃荡条件下与呈T形挡板形式的刚性多孔结构相互作用。使用任意拉格朗日-欧拉方法来跟踪界面波和自由面波的演化，Navier Stokes和Brinkman方程分别控制不可压缩流体的流量和通过多孔区域的流量。为了观察层状流体和具有多孔结构的界面波的相互作用，模拟了一系列设置案例。在各种设置配置下，分析了多孔结构的效果及其在阻尼相关晃动波和罐壁上的冲击压力方面的功效。
