Particle Deposition Mechanisms: Impaction

Impaction on Cylinder in Cross Flow

For particle impaction on a cylinder in cross flows, Langmair and Bladgett (1948) suggested

where an inviscid flow model was used. Similarly, Davies (1952) used a viscous flow model and found

Here a Reynolds number less than 1 is assumed.
