Computer simulation of swarming with aggregation of particles in dispersive systems

Abstract

In the previous works a systematic analysis of swarming processes, accompanied by particles aggregation with the formation of high-order clusters in dispersed flows, has been carried out. As a result of the analysis, it was proposed to consider three main swarming mechanisms. However, only the inertial mechanism was previously considered in detail. In the submitted work, this approach has been firstly adapted to simulating swarming according to the attractive mechanism in a dispersed system with allowance for the aggregation process. The research novelty, peculiarity, and originality of this development lie in that the phenomenon of swarming, accompanied by aggregation, arising under the influence of attraction centers, is modeled using a special probabilistic calculation scheme that is allowing to offer a universal approach to modeling attractive swarming under different physical nature of the interaction. The paper presents the algorithm, results of numerical experiments and gives their brief interpretation.
