transonic flow; viscous inviscid interaction; boundary layer; dense gas

Abstract:
Transonic flows through channels which are so narrow that the classical boundary layer approach fails are considered. As a consequence
the properties of the inviscid core and the viscosity dominated boundary layer region can no longer be determined in subsequent steps but have to be calculated simultaneously. The resulting interaction problem for laminar flows is formulated for both perfect and dense gases. Representative solutions including the internal structure of pseudoshocks and the chocking phenomenon will be presented.
