Kinetics of growth of chain aggregates in magnetic suspensions

Theoretical study of the kinetics of the growth of chain aggregates in suspensions of magnetizing non-Brownian particles is performed. An analytical model for calculating the time-dependent distribution function over the number of particles in the chains is developed and computer experiments on the kinetics of the aggregation of these particles are carried out. Results of calculations using an analytical model are in good agreement with the data of computer experiments when the volume concentration of particles is in the range of 1-2%, which corresponds to many modern magnetorheological suspensions. This allows us to recommend the developed mathematical model as a basis for describing kinetic phenomena in magnetorheological suspensions with low or moderate particle concentrations.
