中文摘要: |
应用空气动力学中的TVD格式构造了用于溃坝水流计算的显隐格式,模拟瞬间全溃时洪水波的运动,给出了与分析解的比较及多种数值试验,结果表明这类格式精度高,稳定性好,不产生虚假的数值振荡,对溃坝涌波具有较强的捕捉能力。 |
英文摘要: |
In this paper, explicit and implicit TVD schemes for computation of aerodynamic are used to simulate the 1-D unsteady open channel flow of sudden dam break. The calculation resuls are compared with analytic solutions and some other results. It is demonstrated that higher accuracy, good stability and non-oscillatory predictions are obtained and good shock-capturing ability is shown. |
