Demo dataset for harmonic-regression flow decomposition

This dataset contains a reduced CFD dataset for harmonic-regression-based decomposition of impeller-driven flows. The dataset includes time-resolved velocity fields and associated quantities required to reproduce the harmonic decomposition into mean, phase-locked, and residual components. To reduce storage requirements and enable fast execution, the dataset is obtained via temporal subsampling (Δt increased by a factor 16) from a larger simulation dataset, while preserving the relevant statistical and spectral features. The dataset is intended for demonstration and reproducibility of the methodology implemented in the associated GitHub repository.
