Fingering versus stability in the limit of zero interfacial tension
The invasion of one fluid into another of higher viscosity in a quasi-two dimensional geometry typically produces complex fingering patterns. A rich variety of patterns were characterized by the viscosity ratio between the inner and the outer fluid.
Fractal growth viscous fingers: quantitative characterization of a fluid instability phenomenon
Water was used to push a more viscous but miscible, non-newtonian fluid in a Hele-Shaw cell. The resulting viscous finger instability was found to be a fractal growth phenomenon. Reproducible values of the fractal dimension were found and were interpreted using a modification of the diffusion limited aggregation model.
