In particular, the mesoscale structure such as particle clusters makes the two-phase flow system have unique physical properties, which has brought a great challenge to the experimental and theoretical research. Thus, it is very important to study the mechanism of particle clusters. We propose a parameterless algorithm for particle cluster identification from the view of microstructure, which also gives a strict definition of particle clusters. Based on the definition of particle clusters and the method of parameterless identification, a kinetic model of clusters based on stochastic process is proposed, where the evolution of the clusters is regarded as a stochastic process. The dynamic model of cluster evolution is established at mesoscopic scale with the mathematical tool of stochastic process. | | | |
