Experimental studies on dispersion of fine non-spherical particles in enclosed spaces
Study on the fine particle dispersion in the room is very important for creating and maintaining a healthy indoor environment.An experiment of a carbon nanofiber material blown in smoke box was taken and the mass concentrations of the aerosol formed by this material were measured.Dispersion process of this material in the smoke box was simulated by random walk model,spherical particles aerosol dispersion model and non-spherical particles aerosol dispersion model,respectively.The setting velocities of the aerosol in the smoke box were calculated according to the mass concentrations at different times and the influences of gravity and non-spherical particles shape on its dispersion process were analyzed in theory.
