Laminar Boundary Layers in the Neighborhood of Abrupt Spatial Disturbances


Tyson, Thomas Janney (1967) Laminar Boundary Layers in the Neighborhood of Abrupt Spatial Disturbances. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/S72R-AM75.


Supersonic, steady laminar boundary layers exhibiting "strong" local interaction with the outer flow are considered. The general behavior of such flows on a flat adiabatic plate are studied by means of the "moment method" equations and by finite difference solutions of the full boundary layer equations, including the transverse momentum equation. A one-parameter family of "free interaction" solutions is generated with the finite difference approach. These include separated reverse flow solutions. The infinite plate solution is established from the leading edge through weak interaction by both techniques. Expansive corner flow solutions are developed using both methods. In the "moment method" study the nature of the leading edge, Blasius point and "critical" line singularities is developed by numerical investigation.
