【Abstract】 In this paper we analyses the viscous-inviscid interactive problem for three dimensional transonic flow. A suitable choice of inputs for the boundary layer equations in the transonic regime was proved. Based on the multigrid of FL027, partial fine mesh was implemented. Numerical solutions about M6 and F1 wing are presented using full potential equation and an inverse integral three dimensional compressible turbulent boundary layer code and compared with experimental data. It shows that the semi-inverse code which is suggested in this paper can be applied to design for weak shock.更多还原
