Abstract
The excitation of elastic vibrations of fibers upon inertial deposition of submicron aerosol particles in the course of gas filtration through fine-fiber filters has been considered. Equations describing the dynamics of the interaction of several aerosol particles with a fiber have been derived. It has been shown that, in the case of heavy particles and long fibers, particles that have been previously deposited onto the fibers can be knocked-out upon an impact of a fast particle. Moreover, it has been demonstrated that fast particles can penetrate through traps consisting of several fibers due to the deformation of the latter. All these processes may have a substantial effect on the filtration performance in the inertial regime.
