Direct numerical simulations of turbulent von Kármán flows and spectral space analysis

This dataset was generated from direct numerical simulations (DNS) of turbulent von Kármán flows in a cylinder using the Nek5000 solver. The dataset includes instantaneous velocity field files and postprocessing configuration files, mean velocity fields (.mat format), global helical-wave energy spectra at different Reynolds numbers (.mat format), and energy transfer functions (.mat format). These data can be used to reproduce and verify the results presented in the associated publication, as well as for visualization of the instantaneous velocity fields.
