Interacting laminar boundary layers of dense gases

  • A. Kluwick
Part of the Acta Mechanica book series (ACTA MECH.SUPP., volume 4)

Summary

The concept of triple deck theory is applied to study laminar interacting boundary layers of dense gases in external subsonic, supersonic and transonic flow. If the flow outside the boundary layer is either purely subsonic or purely supersonic the unusual thermodynamic properties of dense gases do not enter the description of interaction processes to leading order thus leaving the basic scaling laws of standard triple deck theory unchanged. This is no longer true in the transonic flow regime where the streamwise extent and, more important, the magnitude of the induced pressure disturbances are seen to depend on the size of the fundamental derivative Γ. The size of Γ also strongly influences the distance from the wall at which nonlinear cumulative effects lead to a significant distortion of outgoing pressure waves generated by supersonic interacting boundary layers.
