摘要本文讨论了均匀制动和稳定转弯时，有隔板的矩形道路集装箱内液体晃动的动力学问题。分析稳态和数值瞬态解给出的液体高度，力和倾覆力矩的液体上的容器体。研究了隔板数目、隔板上开孔尺寸和位置对分离效果的影响。液体的瞬态响应通过不可压缩的2-D Navier-Stokes方程、连续性方程和自由表面微分方程的数值解获得。一个修改的标记和细胞的技术，特别注意边界条件和保持质量守恒的流量通过校正的液体高度，采用作为一种方法的数值解。据作者所知，本文是第一个报道的研究复杂的晃动现象，在容器中的分离壁，基于完全非线性流体动力学方程的解决方案。所采用的方法允许一个更准确地预测晃荡载荷和更广泛的输入参数比线性理论可以做的。
Abstract Dynamics of liquid sloshing in compartmented and baffled rectangular road containers for uniform braking and steady cornering manoeuvres is presented and discussed. Analytical steady-state and numerical transient solutions are given in terms of liquid height, forces and overturning moments exerted by the liquid on the container body. The influence of the number of separating walls, size and location of orifices in the separating walls is studied. The transient response of the liquid is obtained by a numerical solution of the incompressible 2-D Navier-Stokes, continuity, and the free-surface differential equations. A modification to the Marker-and-Cell technique, with special attention to boundary conditions and maintaining the mass conservation of the flow through a correction for the liquid height, is adopted as a method of numerical solution. This paper, as far as the authors know, is the first reported study on the complicated sloshing phenomena in containers with separating walls, based on the solution of the fully nonlinear hydrodynamic equations. The methodology adopted allows one to predict sloshing loads more accurately and for a wider range of input parameters than linear theories can do.
