摘要
出于流体数值模拟中对高精度离散格式的需求,提出了一种基于NVD性质的混合型格式。算例表明,与其他高精度格式相比,该格式使用简单、精度高、稳定、实用、有效。
A new scheme for convection term discretization is developed based on the behavior of well-known NVD scheme. The new scheme is a combination of several simple common used schemes. It can not only preserve high-accuracy in smooth region of fluid, but also keep non-oscillatory in confusion region. By comparison with some other high-accuracy schemes, it is clearly indicated that the proposed scheme has two characteristics： simple and higher accuracy.
