| 摘 要： | 对一类高阶、高分辨率的ENO格式进行了较为详细的讨论。通过一些典型算例的应用和同常用TVD类型格式的比较 ,说明了在计算中采用高阶格式分辨复杂流动结构的优越性。在对格式应用分析的基础上 ,指出了格式应用中需注意的问题。通过定量分析说明 ,高阶ENO格式在计算中 ,不但能够减少网格规模 ,而且能够明显提高计算物理量 ,特别是其导数的计算精度

| Abstract: | A class of high order and high resolution ENO schemes is carefully studied and analyzed Through using ENO schemes to calculate some model problems and comparing the results with common TVD scheme, it shows the advantages of high order schemes in calculating complex flow problems Through analyzing the results and problems in calculation, some cautions are given It also shows that high order ENO schemes can not only decrease the magnitude of mesh, but also improve the accuracy of parameter and its' derivative in calculation |
