Statistical data

In this section the relevant statistical data for the diffuser computed with Alya is given. The reported data is the one mentioned in Table 2 of the list of desirable quantities (PDF) and also specified here.

The data is available as:

  • In CSV (text) format as profiles along characteristic lines of the diffuser
  • In CSV (text) format as contours along characteristic planes of the diffuser.
  • In HDF5 (binary) format as volumetric data.

Other turbulent statistics

Other relevant statistics from the database are presented in this section. In particular, the turbulent kinetic energy (TKE) and the characteristic length scales (i.e., the Taylor micro-scale and the Kolmogorov length-scale ) are presented in Fig. 17 along some characteristic contours of the diffuser.

Profile data

The profile data is thought to match that of the UFR_4-16_Test_Case and the experimental data. Text files (in CSV format) are provided at the streamwise locations x/h=0, 2, 4, 6, 8, 10, 12, 14, 15.5, 17, 18, 20 and 22 at the following spanwise locations z/B=0.25, 0.5, 0.75 and 0.875. Some of these profiles are also plotted below.
