溃坝涌波的数值模拟

Numerical Modelling of Bores due to Dam-break

本文利用气体动力学中新近提出的TVD显格式对五个溃坝涌波的模型问题进行数值求解。数值结果表明,这类格式具有高分辨率、高精度、不产生虚假振动而且适应性强。

In this paper TVD explicit schemes developed recently in CFO are used to simulate five models of bores due to dam-break. Numerical experiments are presented to demonstrate that they achieve high resolution and generate no spurious oscillations and to show the versatility of the schemes.
