title = "Subsonic boundary-layer Wavefront spectra for a range of Reynolds numbers",
abstract = "Aero-optic measurements of turbulent boundary layers were performed in wind tunnels at the University of Notre Dame and California Institute of Technology for heated walls at a range of Reynolds numbers. Temporally resolved measurements of wavefronts were collected at a range of Mach numbers between 0.03 and 0.4 and the range of Reθ between 1,700 and 20,000. Wavefront spectra for both heated and un-heated walls were extracted and compared to demonstrate that wall heating does not noticeably alter the shape of wavefront spectra in the boundary layer. The effect of Reynolds number on the normalized spectra was also presented, and an empirical spectral model was modified to account for Reynolds number dependence. Measurements of OPDrms for heated walls were shown to be consistent with results from prior experiments, and a method of estimating OPDrms and other boundary layer statistics from wavefront measurements of heated-wall boundary layers was demonstrated and discussed.",
