A numerical algorithm for solving equations of fluid dynamics for the case of a stable stratified flow with a bluff body in the form of a thin vertical barrier generating internal waves is developed and verified with the use of the OpenFOAM software. Numerical simulations of this flow are performed for different Froude numbers for steady and unsteady regimes of wave breaking; it is demonstrated that the results predicted by the proposed algorithm are qualitatively consistent with other available data. The reasons for the differences in the computed drag coefficient from the data obtained previously are discussed.

具有障碍物的分层流模拟算法的开发及其对垂直障碍物流的验证

开发了一种数值算法，用于求解带有钝壁体的稳定分层流情况下的流体动力学方程，该壁体为薄的垂直屏障，会产生内部波，并使用OpenFOAM软件进行了验证。在不同的弗洛德数下，对于稳定和非稳定的波浪破坏状态，进行了这种流动的数值模拟。结果表明，所提算法预测的结果在质量上与其他可用数据一致。讨论了从先前获得的数据计算出的阻力系数不同的原因。
