This study examines the corrolation in the aggregationspeed of micrometer-sized particles, when subjected to different parameters, the results are processed with simulations. The study includes general theory regarding the various parameters, simulations of them compared with each other, to determine the way in which they influence they have, both individually and when put together. The parameters used are Random walk, gravitation and electrostatic force. The focus of the study is specifically to determine, in what degree the electrostatic force has on the aggregationspeed. From our simulations we can conclude, that the electrostatic force has a significant influence on the aggregationspeed of the particles, and that the other two parameters has no significant influence, when dealing with small particles. Our study does not contain any conclusions on the scale of the other parameters, when the particles are above micrometer-size.This study examines the corrolation in the aggregationspeed of micrometer-sized particles, when subjected to different parameters, the results are processed with simulations.
