Statistical data
Volume data
Volumetric time averaged statistics are available in the database. The data is stored in multiple files such that each .pyfrs file contains one quantity. The files which are named avg-xxxx.pyfrs can be interrogated following the guidelines in storage format section. The statistical quantities listed in section 3 (tables 1 and 2) of the document - list of desirable and minimum quantities to be entered into the KB Wiki, are directly provided or can be calculated from those provided following the approach described in the appendix of the document. For example, avg-u.pyfrs is the average streamwise velocity, where as the Reynolds stress, , can be calculated using the data from avg-uv.pyfrs, avg-u.pyfrs and avg-v.pyfrs.
