7.2.2 Interception

The particles when entrained in the streamlines of air are collected by contact with the fibers. They are said to be intercepted. The streamline of air flow is at a distance of dp/2 from the fiber surface. This is a limited condition for the deposition of the entrained particles as they pass a cylindrical fiber. Then, the collection efficiency due to interception may be written as

7.2.3 Diffusion

Small particles display Brownian motion and thus may be collected on the surface of the fibers as the particles are displaced from their median center of location. If the displacement of the particle is 2X o, the collection efficiency due to diffusion may be written as

where DBM = CKT /3π μdp = Diffusivity of the particle
