【摘要】 根据有限体积法的思路,采用加权平均格式(WAF 格式)计算界面通量,HLL 方法计算黎曼近似解,得出了一种非分裂的高分辨率二维溃坝数学模型。通过与几个经典的验证模型比较,表明加权平均格式在捕捉激波,保持间断波形上有很好的效果,能够较好地模拟溃坝波的演进过程。更多还原

【Abstract】 Based on spirit of FVM method,one unsplit high-resolution two-dimensional dam-break numerical model was presented by adopting weighted average flux(WAF)scheme for face flux and HLL method for approximate reimann solution.The present numerical method was applied to some different benchmark problems and is confirmed to be effective in capturing shocks and keeping the wave shape and is good at simulating the dam-break process.更多还原
