The Second Moment of the Distribution Function of Nanoparticles in a Limited Region and Their Brownian Diffusion

Journal of Engineering Physics and Thermophysics Aims and scope

The change of the second moment of the distribution function of nanoparticles in a square under the influence of Brownian diffusion has been studied numerically and analytically. It is shown that the second moment of the distribution function of nanoparticles in an equilibrium system is independent of time, which is an important factor to be taken into account in processing experimental data. It has been established that the second moment of the function of nanoparticles distribution in a nonequilibrium spatially limited system depends on time, with this dependence being nonlinear.
