Abstract
We study traveling time and traveling length for tracer dispersion in
two-dimensional bond percolation, modeling flow by tracer particles
driven by a pressure difference between two points separated by
Euclidean distance r. We find that the minimal traveling time t(min)
scales as t(min)similar to r(1.33), which is different from the scaling
of the most probable traveling time, (t) over tilde similar to r(1.64).
We also calculate the length of the path corresponding to the minimal
traveling time and find l(min)similar to r(1.13) and that the most
probable traveling length scales as (l) over tilde similar to r(1.21).
We present the relevant distribution functions and scaling relations,
