Exp: 2-D Rounded Backstep with Separation, Reattachment, and Recovery

Return to: Data from Experiments - Intro Page

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

These experimental data are for a subsonic rounded backstep at 5 different Reynolds numbers, with separation, reattachment, and recovery. Mach number was less than M=0.06.

Documentation for the experiment can be found in:

• Song, S. and Eaton, J. K., "Reynolds Number Effects on a Turbulent Boundary Layer with Separation, Reattachment, and Recovery," Experiments in Fluids 36, 2004, pp. 246-258; doi: https://doi.org/10.1007/s00348-003-0696-8.
• Song, S., "Reynolds Number Effects on a Turbulent Boundary Layer with Separation, Reattachment, and Recovery," PhD Thesis, Stanford University Technical Report TSD-146, April 2002, UMI Number 3048621.

The data are provided in a single gzipped tar file, which also includes a README file. The four Reynolds numbers (given in terms of Re_theta) are: 1100, 3400, 7100, 13200, and 20100.
