Persistence in cluster-cluster aggregation.
Persistence is considered in one-dimensional diffusion-limited cluster-cluster aggregation when the diffusion coefficient of a cluster depends on its size s as D(s) approximately s(gamma). The probabilities that a site has been either empty or covered by a cluster all the time define the empty and filled site persistences. The cluster persistence gives the probability of a cluster remaining int...
متن کامل0 N ov 2 00 1 Persistence in Cluster – Cluster Aggregation
Persistence is considered in diffusion–limited cluster–cluster aggregation, in one dimension and when the diffusion coefficient of a cluster depends on its size s as D(s) ∼ s . The empty and filled site persistences are defined as the probabilities, that a site has been either empty or covered by a cluster all the time whereas the cluster persistence gives the probability of a cluster to remain...
متن کاملCluster-cluster aggregation in binary mixtures
The structure and aggregation kinetics of three-dimensional clusters composed of two different monomeric species at three concentrations are thoroughly investigated by means of extensive, large-scale computer simulations. The aggregating monomers have all the same size and occupy the cells of a cubic lattice. Two bonding schemes are considered: (a) the binary diffusion-limited cluster-cluster a...
متن کاملA scaling correction in cluster-cluster aggregation
A general correction term in the radius of gyration ~caling law is discussed. The work incorporates the finite size effect considered by Ball and Jullien (J. Ph_»s. Left. Fiance 45 (1984) L1031j and is a potentially useful extension of their analysis to polydisperse systems. Numerical simulations verify these re~ults for one particular model, and demonstrate the remarkable
متن کاملPercolation in cluster-cluster aggregation processes.
Numerical simulations of Diffusion-Limited and Reaction-Limited ClusterCluster Aggregation processes of identical particles are performed in a twodimensional box. It is shown that, for concentrations larger than a characteristic gel concentration, the morphology of the resulting spanning cluster at the gel time tg exhibits a crossover length Lc between percolation (l > Lc) and aggregation (l < ...
