本文提出了一种非结构化网格自适应方法,用于非定常高速可压缩Navier-Stokes方程的数值模拟,包括在三维复杂区域中存在强激波的爆炸和爆炸。我们的想法是确定关键物理的位置本地,然后重新网格这些区域的基础上解决方案导出的度量。该方法确保了几何保真度和网格有效性,特别是对于复杂几何形状附近的区域,这一直是网格自适应的一个挑战。提出的自适应适用于爆炸波传播的模拟,并与文献中的可用数据进行比较。结果表明,该方法对复杂三维区域的计算流体动力学(CFD)问题具有很好的鲁棒性和有效性。
We propose an unstructured mesh adaptation approach for unsteady high speed compressible Navier–Stokes applications involving blasts and explosions with the presence of strong shock waves propagating in three dimensional complex domains. The idea is to identify the locations of critical physics locally and then re-mesh these regions based on solution derived metrics. The approach ensures both geometry fidelity and mesh validity, especially for areas near complex geometries, a task that is always a challenge in mesh adaptation. The proposed adaptivity is applied for simulations of blast wave propagations and compared with available data in literature. The results show that the proposed method is fully robust and efficient for computational fluid dynamics (CFD) problems in complex three-dimensional domains.
