SimulationEnd-to-end diffusion-limited aggregation of an ideal, monodisperse pectin species with variable probability of interrmolecular crosslinking has been simulated on a lattice. The aggregate was fixed on
In this simulation, the initial aggregate is set to be the bottom row of an NxN lattice. Particles are launched from a random cell in the top row. A particle's random walk is set to have the following probabilities: up: 0.15, down: 0.35, and left or right: 0.25. The particle ...

Diffusion Limited Aggregation(DLA) is the process whereby particles moving in a random path due to Brownian motion cluster together to form aggregates. The result is a beautiful fractal computer generated pattern of aggregated particles. This implementation of DLA is very powerful and makes full use...
8.1 Diffusion-Limited Aggregation 8.1.1 Basic Idea 时光易逝,容颜易老?且看度娘怎么说: 首先置一初始粒子作为种子,在远离种子的任意位置随机产生一个粒子使其做无规行走,直至与种子接触,成为集团的一部分;然后再随机产生一个粒子,重复上述过程,这样就可以得到足够大的DLA团簇(cluster)。 君未尝与吾相知,亦无所怨...
Monte carlo simulationAbsorbing stateWe model polymers with anisotropic sites on a square lattice, consisting of head monomers that are hydrophobic (labelled as A) and neutral tail monomers (labelled as B). Our study focuses on diffusion-limited aggregation through on-lattice simulations involving ...

We study a percolation transition (PT) as a function of the aggregation stepin a diffusion-limited cluster aggregation model, in which cluster velocity$v_s$ depends on cluster size $s$ as $v_s \\sim s^{\\eta}$. We find that whenparticles are Brownian, corresponding to the case $\\...
In the case of DLA, modern applications have investigated the simulation of different processes such as the formation of fractal impurity networks in nematic liquid crystals [13], polymers flocculation [14], nano-particles growth [15], wax/asphaltene aggregation [16], dendrite growth of magnetic ...
