Non-intrusive optical approach was used to study the regions of the amplified turbulence inside the externally forced boundary layer. Spatially-temporallyresolved wavefronts in the spanwise direction were collected and analyzed. The external forcing …
An optical investigation of an externally forced boundary layer is presented. Measurements were conducted in Notre Dame’s Compressible Shear Layer Facility. The forced shear layer created an organized spatially-temporally-varying external flow …
An investigation of large-scale boundary layer structure using two simultaneously sampled streamwise oriented apertures is presented. Measurements were conducted in Notre Dame’s Tri-Sonic facility at M = 0.5 at varying sampling frequencies and …
An investigation of large-scale boundary-layer structures using optical wavefront sensing techniques is described. Measurements were conducted in Notre Dame’s Tri-Sonic facility at M = 0.4 and 0.5 with a range of sampling frequencies and spatial …
