An Analysis of Wave Interactions in Swept-Wing Flows

Abstract

Crossflow instabilities dominate disturbance growth in the leading-edge region of swept wings. It is well known that streamwise vortices in a boundary layer strongly influence the behavior of other disturbances. Amplification of crossflow vortices near the leading edge produces a residual spanwise nonuniformity in the mid-chord regions where Tollmien-Schlichting (T-S) waves are strongly amplified. Should the T-S wave undero double-exponential growth because of this effect, the usual transition prediction methods would fail. Thus it is important to study interactions of this sort and to develop more realistic criteria for transition prediction.
