The interaction of diffusional and gravitational particle transport was determined by studying with optical instruments concentrations during passage of monodisperse polystyrene and sebacate aerosols through filters. Particle losses in the filters due to simultaneous diffusional and gravitational particle transport onto filter surfaces can be described by [image omitted] Although deposition due to pure diffusional particle transport dD or pure gravitational particle transport dG exhibits a different time dependence in filters differing from one another as much as cylindrical tubes, granular beds of spherical glass beads, and human lungs, and although the particle size of minimum deposition varies among these filters, this empirical equation holds for particle deposition in all of these filters. This equation can thus account for simultaneous diffusional and gravitational particle transport on any surface. |
