Hypersonic boundary layer data

Hypersonic turbulent boundary layer turbulence profiles for flow over a smooth wall. This PIV data was published in Williams et al. (2018) — see below. Three PIV measurement cases (Cases 2-4) are included in this dataset.

Data files:

Data are available in ‘.csv’ or Matlab formats. In the latter case, the flow conditions are found within the data structure ‘Cond’ and wall-normal profiles are within the data structure ‘Prof’.  Please refer to the README file and the original paper for details on each parameter and its calculation.

For more details or questions please contact  O. Williams.
