Abstract
The microprocesses of the nanoparticles interaction with a condensed solvent are investigated and simulated by the molecular dynamics method. It is shown that the autocorrelation function of random force acting on a particle from the medium contains besides customary-correlated term also the exponential contribution. The space-time correlation function of the response of the medium velocity field to particles motion is calculated. The peculiarities of the behavior of this function in systems with various parameters are investigated. The perturbation wave spreading with sound speed from moving nanoparticle is registered. For massive nanoparticles the presence of the second maximum of the correlation function is revealed.
