ABSTRACT

The aim of this work is to simulate the complex 3D hydrodynamics inside free-surface anti-roll tanks with obstacles and side sub-compartments. The case studies comprise a rectangular tank, a tank with a C-shaped section and a rectangular tank with baffles, for which experimental results are provided. The simulations have been performed for 3 and 6 degrees of roll, and for various filling levels. The Open Source Computational Fluid Dynamics (CFD) tool OpenFOAM has been used to carry out the simulations. Various turbulence models and boundary condition implementations have been used. It is shown in the paper that the k-ω SST model with slip boundary condition is the one that provides the best trade-off between accuracy and computational efficiency. In order for present results to be easily reproducible, the simulations files, also including the geometrical ones, are provided as supplementary material.

具有 3D 动力学的自由表面防滚水箱引起的流体动力扭矩的 CFD 计算

摘要

这项工作的目的是模拟带有障碍物和侧面子隔间的自由表面防滚罐内复杂的 3D 流体动力学。案例研究包括一个矩形罐、一个C形截面的罐和一个带挡板的矩形罐,并提供了实验结果。已经针对 3 度和 6 度的滚动以及各种填充水平进行了模拟。开源计算流体动力学 (CFD) 工具 OpenFOAM 已用于进行模拟。已经使用了各种湍流模型和边界条件实现。论文中表明k - ω具有滑动边界条件的 SST 模型是在精度和计算效率之间提供最佳折衷的模型。为了使当前结果易于重现,模拟文件,也包括几何文件,作为补充材料提供。
