| 摘 要： | 本文从标量形式的ＵＳＬＩＰ格式出发，从理论上分析了通量限制器与ＬＥＤ性质和空间离散精度的关系。利用Ｒｏｅ平均矩阵的Ｕ特性和广义数值Ｒｉｅｍａｎｎ不变量的概念，将此类格式应用于二维翼型跨声流场的数值模拟，针对提供的来流条件，考查了不同的通量限制器对流场计算精度的影响。

| Abstract: | On the base of scalar USLIP scheme,the paper analyses the relations between flux limiters and accuracy of spatial discretizations.Adopting the U property of Roe average matrix and the general numerical Riemann invariants,this kind of difference scheme is applied to numerical simulation of two dimensional transonic airfoil flow field,within the initial condition of this paper,the relations between flux limiters and the accuracy of numerical simulation are investigated. |
