The effect of the rotating flow upon the diffusion?-limited aggregation (DLA) is investigated by using a Monte Carlo model. The growth process is governed by therotating flow and the diffusiorr. The convective diffusion fielcl is simulated by thebiased-random walker. With varying direction and strength of the rotating flow,distinct morphologies develop. By introducing a tangential flow, the diffusion-limitedaggregatuon changes into a single arm which is oppositely vorlical to the tangentialflow. In the case of both radial and tangential flows, the DLA pattern changes into amultiarm structure.DLA, ballistic model, fractal, random walk
