Kinetic closure of turbulence: collision-side modeling beyond the filtered BGK–Boltzmann equation - dataset

This dataset supports the article Kinetic closure of turbulence: collision-side modeling beyond the filtered BGK--Boltzmann equation by Francesco Marson and Orestis Malaspinas. The companion code release is deposited on Zenodo at 10.5281/zenodo.20283413. The associated arXiv article is available at https://arxiv.org/abs/2605.19796, DOI 10.48550/arXiv.2605.19796. The package contains processed simulation data, plotting and post-processing scripts, verification wrapper scripts, file checksums, representative VTK snapshots, and one rendered cylinder-wake animation for three numerical cases: the Taylor-Green vortex, flow around a circular cylinder, and the lid-driven cavity. The data reproduce the plotted statistics, spectra, and data-derived table values used to compare kinetic-closure lattice Boltzmann models with Smagorinsky and regularization-based reference models. Representative VTK snapshots and the included cylinder animation support inspection of the field data used for the visualization comparisons. High-count processed outputs are stored as compressed archives under data/. Representative visualization snapshots are listed in docs/VTK_SNAPSHOTS.tsv. File sizes and SHA256 checksums are recorded in MANIFEST.tsv. 🛑 License and ethical-use restriction: this dataset package and any included research materials are distributed under the End-User Ethical Dataset and Software License Agreement (EEDSLA), Version 1.0, May 2026.
