Particles are collected when the streamline brings the particle center to within one particle radius from the fiber surface. This effect is described by a dimensionless interception parameter R, which is the ratio of particle diameter dp to fiber diameter as follows:

Assuming Kuwabara flow, ^inter is given by the following equation:


Inertial impaction is a significant collection mechanism for large particles, high gas velocities, and small-diameter fibers.
