Canonical shock/turbulence interaction

A collection of averaged data for the DNS cases in Larsson et al (JFM 2013) and Larsson and Lele (PoF 2009) can be downloaded as a tar-file here. Once unpacked, the files are in ASCII format with a header that describes the contents of each file. This header should be read as follows:

  • u means the average of the shock-normal velocity, u-F means the density-weighted (Favre) averaged value.
  • u_x means the average of the shock-normal derivative of u; y and z are in the plane of the shock.
  • r’r’ means the average of the density fluctuation squared (i.e., the variance).
  • u”v”-F means the density-weighted average of the u-fluctuation times the v-fluctuation, where the fluctuation is defined with respect to u-F and v-F.

Note that the data in these files were averaged over a small set of 3D solution snapshots, so the profiles are relatively noisy. The Reynolds stresses (“Rij”) have units of velocity squared, i.e., without the density. Some quantities should be zero by symmetry or due to the periodic boundary conditions, but are included anyway.
