Abstract: In order to evaluate the migration of aerosols in porous media driven by gases, a dual porosity dual permeability mathematical model is proposed in symmetric cylinder coordinates.The processes of permeation, absorption, diffusion and heat exchange are considered. Calculated results show that aerosols could be contained in porous media well. Simulating experiments confirmed the prediction.

Key words: aerosol, porous media, migration, numerical simulation, dual porosity
