Electrostatic Forces

Aerosol particles can acquire an electrostatic charge either during their generation or during flow through a gas stream. Likewise, the filter fibers can acquire a charge due to the friction caused by a gas stream passing over them. The following three cases can occur:

1. Charged Particle-Charged Fiber


4Qq 3^ddfVg

where Q is the charge per unit length of the fiber and q is the charge on the particle. 2. Charged Fiber-Neutral Particle


where is the dielectric constant of the particle. 3. Charged Particle-Neutral Fiber v 1/2
