In this work we examined the aero-optical component of the jitter that results from a forced shear layer. Full 2D wavefronts were collected in Notre Dame's Tri-Sonic facility with the high speed flow set at $M = 0.6$ and the low speed flow set at $M …
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 …
