Compressible Boundary Layer Receptivity and Instability
Abstract
A high quality flow has been established in a low turbulence variable geometry (LTVG) 8 x 8' supersonic wind-tunnel at Princeton. In particular, the facility is being operated at very low stagnation pressures (-= 4 psia) giving a large region of laminar flow on a flat plate with laminar boundary layers up to approximately 3rnm thick. Mean profiles, amplitude distributions, two wire correlations and spectra have been mcasured in detail through a Mach 3 boundary layer along the centerline of the flat plate. The initial results are for "naturally" occurring instability and transition and they are being followed by measurements of the forced response from a point source (spark) .1.
