摘要
本文总结了粘流/无粘流的各种计算方法和结果。重点在于介绍定常流动中的弱相互作用。首先叙述了弱相互作用的数学模型。给出了不可压流动和跨音速流动中粘流/无粘流相互作用的某些正耦合的计算结果。讨论了在分离区附近边界层正方法失效的原因。然后介绍了边界层反方法和适用于带分离的流动中半反方法耦合的粘流/无粘流的相互作用方法。文中也简单地总结了三维情况的应用和强相互作用。
Different computational methods and results of viscous/inviscid interaction are reviewed in this paper. The emphasis is placed on introduction to the computation of the weak interaction the steady flow. The mathematical model of the weak interaction is described at first. Using direct coupling some results of viscous/inviscid interaction are given in both incompressible and transonic flow. Discussing why direct mode of boundary layer fails near separation. The inverse mode of boundary layer and the semi-inverse coupling between viscous/inviscid interaction for flow with separation region are then described. Application in 3-D case and strong interaction are also briefly reviewed in this paper.
