论文摘要
本文提出了一种新方法，允许对浸没固体结构与表面波电流之间的相互作用进行数值研究。该方法涉及用于两流体配方的Navier-Stokes方程求解器，其用于接口跟踪的准确保守级别（ACLS）方法。求解器在非结构化网格上概括，从而实现了FSI（流体固定相互作用）的边界拟合实现。当它通过水槽移动时，检查了一个实心，垂直，部分浸没的圆柱体。后者部分充满流水；在液体表面传播的波浪会影响圆柱体。模拟结果包括检查自由表面拓扑，气缸唤醒中的空气夹带和涡度产生，以及固体上的压力分布。数值结果是根据同一作者执行的实验验证的。
This paper presents a new method allowing for a numerical study of the interaction between a submerged solid structure and a current with surface waves. The method involves a Navier-Stokes equation solver for a two-fluid formulation with the Accurate Conservative Level-set (ACLS) method used for interface tracking. The solver is generalized on unstructured grids, thus enabling a boundary-fitted implementation of the FSI (Fluid-Solid Interaction). A solid, vertical, partially submerged cylinder is examined as it moves through the flume. The latter is partially filled with flowing water; waves propagating on the liquid surface impact the cylinder. Simulation results include examination of the free surface topology, air entrapment and vorticity production in the cylinder wake, as well as the pressure distribution on the solid. Numerical results are validated against an experiment performed by the same authors.
