Cunningham slip factor
WebDec 9, 2008 · The drag coefficient on each particle, which is calculated using standard correlations (Schiller Neauman), must be divided by the Cunningham correction factor. … WebIncluded in Equation 1 is the Cunningham slip factor, which should be used with particles that have a diameter less than about 1.5 µm, as the deposition velocity is affected by ‘slip’ at the surface of the particle. The Cunningham slip factor is calculated as follows: When particles are larger than about 75µm, Equation 1 will overestimate the
