Diffusion-limited aggregation in channel geometry
arXiv:cond-mat/0304458 · doi:10.1103/PhysRevE.68.020401
Abstract
We performed extensive numerical simulation of diffusion-limited aggregation in two dimensional channel geometry. Contrary to earlier claims, the measured fractal dimension D = 1.712 +- 0.002 and its leading correction to scaling are the same as in the radial case. The average cluster, defined as the average conformal map, is similar but not identical to Saffman-Taylor fingers.
