摘要
本文为计算三维跨声速粘性-无粘相互作用提供一半逆方法版本。湍流边界层采用积分反方法。证明了对于跨声速流,选取外部流线角α和等价的不可压缩形参作为输入量,边界层积分方程总是双曲型的。无粘外流采用FL027程序。通过粘性-无粘迭代求得小分离区情况下的与实验符合的收敛解。
A version of viscous-inviscid interactive semiinverse code for three dimensional transonic flow is proposed in this paper. Inverse integral method is used for compressible turbulent boundary layer. It is proved that with external streamline angle a and 'incompressible' shape H chice of inputs the integral boundary layer equations are always hyperbolic in the transonic regime. The inviscid calculation is performed using FL027 which is the full potential code. Viscous-inviscid interactive solution which agreed reasonably well with experiments in small attack angle is obtained for the case of small separated region.
