Investigation of the double ramp in hypersonic flow using luminescent measurement systems [PDF]

open access: yes, 2012
Compression ramp flows in supersonic and hypersonic environments present unique flow patterns for shock wave-boundary layer interaction studies. They also represent the generic geometry of two-dimensional inlets and deflected control surfaces for re ...

Asymmetric hypersonic flow [PDF]

open access: yes
A general method for the analysis of the inviscid asymmetric hypersonic flow fields enveloping smooth bodies of general shape is given. The method is based on the assumption of a thin shock layer which yields an expression for pressure in generalized ...
