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

This dataset supports version 2 of the arXiv manuscript Kinetic closure of turbulence: collision-side modeling beyond the filtered Boltzmann equation by Francesco Marson and Orestis Malaspinas. The companion software release is deposited on Zenodo at https://doi.org/10.5281/zenodo.21260883. The associated arXiv record is available at https://arxiv.org/abs/2605.19796, DOI https://doi.org/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 values used to compare kinetic-closure lattice Boltzmann models with Smagorinsky and regularization-based reference models. The revised cylinder-flow dataset includes the reference PIV data used in the manuscript comparisons. Representative VTK snapshots and the included cylinder-wake 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 the included research materials are distributed under the End-User Ethical Dataset and Software License Agreement (EEDSLA), Version 1.1, July 2026.
