| 摘 要： | 应用高精度加权本质无振荡(WENO)格式构造了溃坝水流计算的数学模型,模拟了坝体瞬间全溃时洪水波的运动过程,并将计算值与理论解进行了比较。结果表明,WENO格式精度高,稳定性能好,能够很好地模拟溃坝波的演进过程。

| Abstract: | In this paper,a mathematical model for simulating dam-break flows was set up based on the WENO(Weighted Essentially Non-Oscillatory) scheme,by which the process of flood wave movement caused by sudden dam-break was simulated.Compared with the analytic solutions,the computed results have high accuracy and good stability,and show that the proposed mathematical model based on the WENO scheme can effectively simulate the dam-break flows. |
