| 摘 要： | 从非定常Ｅｕｌｅｒ方程组出发,采用非结构三角形网格,研究二维无粘流动问题的自适应流量修正有限元解。将ＦＥＭ－ＦＣＴ与网格自适应相结合计算了ＮＡＣＡ００１２翼型的三个算例。计算结果与实验及其他计算结果比较,亚音速和超音速绕流符合很好；跨音速绕流情况存在一些差别。

| Abstract: | The solution of compressible flow on unstructured triangular grids in two dimensions is considered.FEM-FCT for the Euler equations are combined with an adaptive mesh regenera-tion procedure and employed in solution of three examples.Comparisons with experiment data or other computational resuIt show good agreement for the subsonic and supersonic flow around NACA0012 airfoil.However.the location of shock-wave has some differeneehrthe transonic flow. |

| Keywords: | compressible flow inviscid flow Euler equations of motion finite element method |
