Storage Format

The statistical data provided is stored in the XML Parallel vtkUnstructuredGrid format, e.g, filename.pvtu [‌1]. The Parallel data format does not actually contain any data but references other serial files (Serial vtkUnstructuredGrid) containing the data for each grid partition used for the computation, e.g., filename_partition_number.vtu. vtu files can be easily read through the open-source Paraview software, a multi-platform application for data analysis and visualization [‌2]. Datasets are delivered as compressed file (.tar.gz).

Statistical data format

The dataset consists of a set of .vtu files:

  • averaged_pressure.vtk: averaged pressure,
  • averaged_velocity_i.vtk: averaged velocity i-th component,
  • Reynolds_stress_ij.vtk: the 6 components of the Reynolds stress tensor,
  • Taylor_microscale.vtk: Taylor microscale,
  • Kolmogorov_length_scale.vtk: Kolmogorov length scale,
  • Kolmogorov_time_scale.vtk: Kolmogorov time scales,

where and range between 1 and 3 and are alias of (streamwise), (normalwise), (spanwise).
