摘要
本文针对再入飞行器的空气动力问题，采用一步和二步有限元格式求解可压缩守恒型Ｅｕｌｅｒ方程，并结合不同的人工粘性模型来捕捉激波，给出了高超声速二维钝头绕流的结果。
n order to solve the aerodynamic problems arising from the re-entry vehicle,one step and two step finite element schemes for the compressible Euler equations are presented,and combined with Lapidus and MacCormack artificial viscosity methiods to capture shock.The results are givin for the hypersonic flow past the blunt body in two dimensions.
