Data for "Spectral-Statistical Filtering for Vorticity-Impulse Force Estimation"

This dataset contains example DNS data and processed outputs for a force-estimation study of incompressible flow past a stationary circular cylinder at Reynolds number 150. The DNS example includes 1002 consecutive velocity-field snapshots (non-dimensional time t* = 700.0 to 725.0, sampling interval Δt* = 0.025) and the direct surface-integrated force history. The processed outputs (660 HDF5 files) cover a parameter grid of spatial resolutions h* = 0.01 to 0.10, temporal resolutions Δt* = 0.025 to 0.3, record lengths L = 512 to 4096, and ten synthetic measurement-noise configurations, including σ_f = 0.075, σ_g = 0.005. Each output file provides drag and lift coefficient time series at several processing stages, per-snapshot field-error measures, and the processing parameters in the file attributes. File formats and naming conventions are documented in the repository description.md. The full DNS field archive is available from the authors upon request
