## Ergodic simulations of diffusion in random velocity fields

AbstractErgodic simulations aim at estimating ensemble average characteristics of diffusion in random fields from space averages. The traditional approach, based…

## Global random walk algorithm for diffusion processes

AbstractThe Global Random Walk algorithm (GRW) performs the simultaneous tracking on a fixed grid of large collections of particles, while…

## Ergodic Estimations of Upscaled Coefficients for Diffusion in Random Velocity Fields

AbstractUpscaled coefficients for diffusion in ergodic velocity fields are derived by summing up correlations of increments of the position process,…
