Compression-driven viscous fingering: Experimental and numerical data

These data are from experiments and numerical simulations of viscous fingering in a rigid, radial, oil-filled Hele-Shaw cell driven by the compression of a connected air reservoir. The methods and data are presented in the authors' joint-submissions and their supporting information:

L. C. Morrow, C. Cuttle, and C. W. MacMinn, Gas compression systematically delays the onset of viscous fingering, Physical Review Letters 131, 224002 (2023).

We here provide all raw data for 2 experimental repetitions and 5 numerical repetitions, over the full range of parameters reported.

See README file for full details.

VERSION 2: The pressure data are now given in the correct units of Pa. Note that the pressure data in Version 1 are identical, except for the fact that they are mistakenly given in units of PSI.
