Va. Kirsh, Gravitational deposition of aerosol particles on a fibrous filter with account for the effect of van der Waals force, COLL J, 63(1), 2001, pp. 68-73
The deposition of inertialess aerosol particles with a finite radius is inv
estigated on fibrous filters under the effect of gravitational and molecula
r forces. It is shown that particles are deposited on fibers from an upgoin
g slow flow as a result of the action of van der Waals forces that balance
the gravitational particle displacement from the flow lines near the fibers
