DEPOSITION OF PARTICLES IN A 2-DIMENSIONAL LATTICE GAS-FLOW

We present Monte Carlo results for the deposition of particles on a li ne, in a two-dimensional semi-infinite flow simulated by a lattice gas automaton. Instead of straight inclined needles, as observed for diff usion-limited deposition with a drift, we obtain a distribution of clu sters which are inclined with an angle increasing linearly with the di stance to the base line. The kinetics is different than in diffusion-l imited deposition, whereas the static properties of the clusters are s imilar.
