Abstract

The coarsening of fractal viscous fingerprinting patterns (FVFP) was investigated in terms of an unforced Hele-Shaw (UHS) flow. Two series of numerical simulations with model B were performed, with FVFPs grown in the experiment and with diffusion limited aggregates as the initial conditions. Breakdown of dynamic scale invariance at large distances is confirmed. The simulations with model Bare in remarkable agreement with experiment on the Hele-Shaw coarsening of FVFPs.
