Exp: Shock Boundary Layer Interaction at M=2.05

Return to: Data from Experiments - Intro Page

The data on this page were provided by Laura Campo and John K. Eaton.

These experimental data are for shock boundary layer interaction (SBLI) flows with M=2.05 freestream in a low aspect ratio geometry, with documentation of the 3-D effects. The oblique shock is generated by a fully spanning 20 deg compression ramp on the top wall of the test section. The flow is documented for two ramp heights, h_ramp = 3mm and 5mm (h_ramp/delta₀ = 0.56 and 0.93), using streamwise-vertical measurement planes at four locations across the span. The data were taken at Stanford University, as described in the reference.

Documentation for the experiment can be found in:

• Campo, L. M., "Effects of Shock Strength, Confinement, and Geometric Perturbations on Shock Boundary Layer Interactions," PhD Thesis, Stanford University, July 2014. (thesis is provided here with permission of the author)

For the baseline experiments, a README file and a tarred, gzipped file with the experimental data are provided here (note most data are in MATLAB files):

• README_baseline.pdf
• Baseline_experiments_3mm_and_5mm_ramps.tar.gz (gzipped tar file, 94 MB)

An uncertainty quantification (UQ) database is also provided, which details the effects of small perturbations to the inlet geometric boundary conditions. A README file and a tarred, gzipped file with the experimental data are provided here:

• README_UQ.pdf
• UQ_experiment.tar.gz (gzipped tar file, 54 MB)
