摘要

在本文中，我们研究了准流体动力学(QHD)方法作为OpenFOAM求解器实现的并行性能的缩放。采用有限体积法对时变偏微分方程进行离散化。作为一个测试水动力问题，我们取一个有界的梯形槽内的内波产生和一组允许内波吸引子演化的参数。采用适当的正交分解对二维和全三维仿真进行分析比较。

OpenFOAM Solver Based on Regularized Hydrodynamic Equations for High Performance Computing

In the paper we investigate scaling of parallel performance for an implementation of quasi-hydrodynamic (QHD) approach as an OpenFOAM solver. Time-dependent partial differential equations are discretized using Finite volume method (FVM). As a test hydrodynamical problem we take internal wave generation in a bounded tank of trapezoidal shape, and set of parameters, which allows internal wave attractors to evolve. Proper Orthogonal Decomposition was applied to analyze and compare 2D and full 3D simulations.
