FCT有限元法数值求解三维可压缩高速无粘流问题

NUMERICAL SIMULATION OF THREE DIMENSIONAL HYPERSONIC INVISCID FLOWS OVER SPACEVEHICLES WITH FCT FINITE ELEMENT METHOD

从Ｅｕｌｅｒ方程出发，利用流量修正有限元法（ＦＥＭＦＣＴ）求解三维无粘流动的高速流场。通过对圆球、简化航天飞机和双子星座飞船返回舱外形的数值模拟证明，这种方法对激波有较高的分辨能力，是一种有效的方法。

FEM FCT is used to solve three dimensional hypersonic inviscid flow.The flow fields around sphere,modified space shuttle orbiter and capsule type vehicle are gained on unstructured tetrahedron grids.The results show that the scheme is valid and has high resolution to shock waves.
