Abstract
The study deals with transonic laminar interacting boundary layers in channels which are so slender that the flow inside the inviscid core region can be treated as quasi-one-dimensional. The resulting interaction equations are found to admit eigensolutions, i.e. solutions for completely flat channel walls, which describe the transition from a supersonic to a subsonic state and can be interpreted as pseudo-shocks. A nozzle type geometry of the channel walls is, however, necessary to achieve a transition from subsonic to supersonic speeds. The interaction equations can then be used to design the nozzle shape such that it generates a desired pressure distribution.
