Salcido Física, Astronomía y Matemáticas brownian coagulation turbulent coagulation Polydispersed aerosols mathematical modelling A mean field model for Brownian and turbulent coagulation of polydispersed aerosols is proposed. This model is based on a discrete balanceequation that gives the rate of change for the number density of particles with diameters within a given range in terms of the rates of formationand loss of particles in all other diameter ranges. A monomer structure for the particles is not considered in this model, differing in this sensefrom the Smoluchowsky theory. Instead, it uses a probabilistic estimate of formation or loss of particles which depends on the diametersranges of the colliding particles. To test this model, five aerosol coagulation experiments, carried out by Kim et al. [1], Rooker and Davies [2],and Okuyama et al. [3] were used to try to reproduce the results. The computer simulation results were found in good agreement with theexperimental data. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57064006 https://www.redalyc.org/journal/570/57064006/ https://www.redalyc.org/journal/570/57064006/html/ https://www.redalyc.org/journal/570/57064006/57064006.epub https://www.redalyc.org/journal/570/57064006/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
