Compressible turbulent plane channel DNS database

The database contains detailed turbulence statistics of compressible turbulent plane channel (TPC) flow, obtained from direct numerical simulation (DNS), solving the compressible Navier-Stokes equations [1,2]. The database contains 25 flow-conditions determined by the corresponding Reynolds and Mach numbers (Retau*, MCLx), covering the range 100 < Retau* <1000 , 0.3< MCLx <2.5.

The directory corresponding to each flow-condition contains 4 subdirectories:
0_GD_global_data
1_PBs_profiles_and_budgets
2_pdfsq_single_variable_pdfs
3_pdfs2q_two_variable_joint_pdfs
each of which contains plain text (.txt.) files. Detailed comments in each file describe its contents, which are space-separated columns. All data can be directly plotted from the files using gnuplot.

Detailed description of the computations and initial physical analysis of the data can be found in [1,2] (both are open access).
