Turbulence Realm turns ordinary fluid-dynamics videos into quantitative insight. Track bubble motion with sub-pixel precision and discover the governing equations of your flow — all on your desktop.
Purpose-built desktop tools that take you from raw video to publishable results — calibration, tracking, modeling, analysis, and export in a single workflow.
Track and analyse the movement of bubbles, droplets, and particles in fluid-dynamics videos. v3.1 adds automatic multi-object tracking (MOT) of every bubble, watershed segmentation, fluid-physics outputs (Re/We/Eo), Eulerian flow fields, event detection, live camera capture, lens-distortion correction, uncertainty propagation, and one-click PDF reports.
Extract a dense velocity field from video using optical flow, fit a SINDy model to discover the governing equations, reconstruct the field, and explore it with rich visualization and physics-informed machine learning.
A complete toolkit for fluid-dynamics video analysis — vision, modeling, analysis, and reproducible export.
Dense velocity fields and object tracking from video, with multiple backends and quality metrics. v3.1 adds automatic multi-object tracking (Kalman + Hungarian MOT) of every bubble.
Fit sparse models from polynomial, Fourier, and combined libraries. Read off the discovered governing equations directly, with cross-validation and library comparison.
Line, multi-point, checkerboard grid, and lens-distortion correction with presets and history.
Vorticity, spectra, POD/DMD, turbulence statistics, Reynolds/Weber/Eötvös numbers, drag, terminal velocity, event detection, and uncertainty propagation.
Train PINNs for Navier-Stokes, autoencoder-SINDy, Fourier Neural Operators, DeepONets, and ConvLSTMs — with uncertainty quantification and ONNX export.
CSV, JSON, Excel, HDF5, Parquet, NetCDF, PNG, PDF reports, MP4.
Provenance metadata — git commit, versions, seed, input hash — embedded in every export.
The same workflow powers both apps — load, calibrate, model, and export.
Open any MP4/AVI/MOV, draw a calibration line of known length, and get real-world units instantly.
Select regions to track, or let optical flow build a dense velocity field across the whole ROI.
Fit a SINDy model, run POD/DMD, compute turbulence statistics, or train a physics-informed net.
Quiver plots, heatmaps, animated fields, and reproducible exports to CSV, HDF5, PDF, and MP4.
Step-by-step guides for both apps — from your first tracking run to discovering governing equations.
Load a video, calibrate, select bubbles, track, and export your first velocity dataset — the full workflow.
