| 摘 要： | 将原来在结构网格中提出的AUSM+(Advection Upstream Splitting Method)格式,推广应用于二维非结构网格中。利用格林-高斯公式对控制体内的变量进行线性重构,获得空间二阶精度,并采用Barth型限制器以抑制数值解的振荡。为提高计算效率,采用了自适应多重网格法。在生成非结构网格时,采用了一种新颖的数据结构——数组链接表。最后给出了NACA0012翼型和带10%鼓包的管道流动的几个Euler方程的算例,并进行了分析比较。

| Abstract: | The AUSM+ scheme which was developed on structured grid has been extended to be used on unstructured grid. The monotone linear reconstruction procedure using Green-Gauss theory is utilized to obtain second order spatial accuracy. Barth's limiter is employed to prevent solution spurious oscillations. An adaptive multigrid strategy is used to accelerate the convergence. Numerical results for several test cases are presented. |
