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:

Volume data

• averaged_pressure.vtu: averaged pressure, ${p}/p_{ref}$
• averaged_velocity_i.vtu: averaged velocity i-th component, ${U}_{i}/u_{ref}$
• Reynolds_stress_ij.vtu: the 6 components of the Reynolds stress tensor, $R_{ij}/(\rho _{ref}u_{ref}^{2})$
• Taylor_microscale.vtu: Taylor microscale, $\eta _{T}/T$
• Kolmogorov_length_scale.vtu: Kolmogorov length scale, $\eta _{K}/T$
• Kolmogorov_time_scale.vtu: Kolmogorov time scales, $\tau _{K}u_{ref}/T$

Surface data

• bottom_wall_averaged_pressure.vtu: averaged pressure, ${p}/p_{ref}$
• wing_averaged_pressure.vtu: averaged pressure, ${p}/p_{ref}$

where $i$ and $j$ range between 1 and 3 and are alias of $x$ (streamwise), $y$ (normalwise), $z$ (spanwise).
