Advective scaling of the axial deformation period of bubbles in a two-dimensional water-saturated porous medium

This dataset contains the frame-by-frame experimental measurements and derived results for 51 bubbles rising through a water-saturated granular packing, used in the study "Advective scaling of the axial deformation period of bubbles in a two-dimensional water-saturated porous medium." It includes the raw front- and rear-end velocity trajectories and bubble volumes measured by high-speed imaging; a per-bubble summary of derived quantities (rise velocity, deformation period, Strouhal number, equivalent diameter, and related time scales); the intermediate signal-processing data (detrended and windowed velocity series and amplitude spectra) for each bubble; and the corresponding waveform and spectrum figures, provided both as individual files and as a combined PDF. A README file describes the folder structure and every column in detail.
