Aerosol Particle Collection by Filters Composed of Fibers Coated with Porous Permeable Shells

Аннотация

Filtration of fine aerosols with model filters formed from composite fibers coated with porous permeable shells (layers) of a discrete structure consisting of finer parallel fibers has been considered. Drag forces and efficiencies of diffusion collection of submicron particles have been calculated as depending on the porosity of the filters, parameters of the shells, and the Peclet diffusion numbers at which the filter performance is substantially increased.
