# 🧪 Rigid-emulsion flow curves near jamming (Dinkgreve et al. 2015, Fig. 2)

`dataset id: dinkgreve2015_fig2`

Steady-state flow curves of castor-oil-in-water emulsions with rigid droplet interfaces (0.4 wt% BSA + 0.4 wt% PGA), digitized from Fig. 2(a) of Dinkgreve, Paredes, Michels & Bonn, Phys. Rev. E 92, 012305 (2015). Seven internal volume fractions from 0.65 to 0.80, spanning the jamming concentration. All supercritical curves are well described by the Herschel-Bulkley equation; the paper uses this dataset to demonstrate universal rescaling of flow curves with distance to jamming.
