Interception

Interception occurs when a particle following a gas streamline comes within one particle radius of a filter. The particle touches the filter and is captured, thus being removed from the gas flow. For a given particle size, there are certain streamlines which will move close enough to a filter so that the particle will be captured. Streamlines further than one particle radius away from a filter will not contribute to the interception mechanism.
