Data for assessing integral time scale estimation from PIV measurements

This dataset contains processed 2D cylinder-wake PIV velocity fields and DNS-based artificial volumetric PIV velocity fields used to support the manuscript titled “The optimal way to determine the Integral Time Scale with the particle image velocimetry.” Raw PIV image files and artificial volumetric particle images are not included due to their large file size. The DNS source data are publicly available from the Johns Hopkins Turbulence Database. Metadata files are included to describe the dataset structure, variable names, coordinate conventions, and unit conversions.
