- Abstract
Numerical simulation of the PM2.5 filter phenomenon in the internal microstructures of fibrous assembly was carried out three dimensionally by discrete element method (DEM). Eulerian method and Lagrangian method were employed to deal with the gas phase and solid phase respectively. By the direct tracking of each of the aerosol particles, the collection efficiencies of PM2.5 were calculated under different conditions. The simulation results show that the collection efficiency of PM2.5 decreases with the increase of porosity (?) and linear density (?), while is found no variation with the change of particle concentration and flue gas velocity.
