| 摘 要： | 在结构网格上提出了一种新的在混合模板集上守恒量插值的非线性权系数计算方法,构造了一种多重加权实质无波动激波捕捉格式,即所谓的MWENO(Multi-Weighted Essentially Non-Oscillatory)格式.与DWENO(Double Weighted Essentially Non-Oscillatory)格式相比非线性权系数的计算不用人为调节.随后文中给出了几个典型算例.通过MWENO格式和WENO格式的计算结果比较,表明MWENO格式具有较高的间断分辨率. |

| Abstract: | A new MWENO (Multi-Weighted Essentially Non-Oscillatory) scheme is constructed on uniformly grids. By using discrete data, the nonlinear weights of state variables interpolating polynomials can be obtained over mixed stencil sets. To contrast with DWENO (Double Weighted Essentially Non-Oscillatory) scheme, the main advantage of MWENO is not need to adjust values of the nonlinear weights artificially. Finally, many classic numerical tests are presented, which show the MWENO scheme is successful and efficient than associated WENO scheme. |
