On the basis of a stochastic system of equations, describing the behavior of the average velocity of nanoparticles, the external field and the internal energy, a synergetic model, which allows in a self-consistent manner to present the modes of the suspended nanoparticles motion, was constructed. Considering the correlation between the times of change of the degrees of freedom the Fokker-Planck equation was obtained, and the corresponding Langevin equation was found. Phase diagram of the system was built and the dependence of steady-state average velocity on the external conditions was found. Within the framework of the phase-plane method the kinetics of the transition between the modes of the nanoparticles motion was investigated.
