Abstract
Diffusion of hollow nanoparticles in low-density and rarefied gases and the viscosity of aerosols with such particles are studied using the previously developed kinetic theory and molecular dynamics method. Nitrogen-based aerosols with hollow and solid aluminum and uranium nanoparticles are considered at a temperature of 300 K and atmospheric pressure. Diameter of the nanoparticles was varied from 5 to 100 nm; the thickness of walls of hollow nanoparticles was 1 nm. It is shown that the diffusion coefficients of hollow nanoparticles always exceed those of solid particles of the same size and the same material, but this difference does not exceed 1%. The viscosity of aerosols with hollow nanoparticles is always lower than of aerosols with solid particles. Using the molecular dynamics method, the diffusion coefficients of hollow and solid nanoparticles of the same diameter and the same material in dense argon are found to be equal.
