Narrative: This proposal for computer service time deals with a                 novel fundamental theory of aerosol collection by porous granular               filters.  The theory outlines an explicit and systematic procedure              for calculating the filtration efficiency.  This theory is free of              any ad hoc assumptions, as well as of the artificial concept of                 single-element efficiency implicit in existing theory.  Theoretical             calculations of the three global aerosol transport coefficients are             proposed, which are based upon a rigorous application of Taylor-Aris            convective-dispersion theory to a lattice model of a porous filter.             These calculations permit rigorous and systematic study of the                  dependence of the filtration efficiency upon the various filtration             operating parameters and aerosol properties.  The importance of the             proposed theoretical research can be related to: (i) establishing               the limitations of existing filtration theory; (ii) interpreting                experimental data; and (iii) optimal filter design.
