Abstract This paper present numerical computations of solitary wave impact on a vertical wall. Different wave breaking cases were studied such as the high-aerated (air-pocket) or low-aerated (flip-through) in order to test the software ability to accurately reproduce the generated wall pressure loads. The numerical toolbox OpenFOAM was used here under the incompressible and compressible assumptions, together with 2D and 3D configurations. First, an idealised test case was used to validate the numerical convergence on an analytical value of the pressure impulse. Pressure impulse convergence was always numerically obtained but the pressure levels never converged under the incompressible assumption. Switching to the compressible assumption, pressure impulse and pressure time series converged both on the idealised test case and on the experimental configuration used. A large variety of spatial and temporal pressure variations were highlighted in this study that enable some physical interpretation of the impact mechanism.

孤子撞击垂直壁的计算：不可压缩和可压缩假设与实验验证的比较

摘要 本文介绍了孤立波对垂直壁面冲击的数值计算。研究了不同的破浪情况，例如高充气（气袋）或低充气（翻转），以测试软件准确再现生成的壁压力载荷的能力。数值工具箱 OpenFOAM 在不可压缩和可压缩假设下以及 2D 和 3D 配置下使用。首先，使用理想化的测试案例来验证压力脉冲分析值的数值收敛性。压力脉冲收敛总是通过数值获得，但在不可压缩假设下压力水平从未收敛。切换到可压缩假设，压力脉冲和压力时间序列收敛于理想化的测试案例和所使用的实验配置。本研究强调了大量的空间和时间压力变化，可以对撞击机制进行一些物理解释。
