Cunningham correction factor
ID: cunningham-correction-factor
The Cunningham correction factor is a numerical factor used in fluid dynamics to adjust the drag force on small particles moving through a fluid, specifically when considering the effects of molecular mean free path relative to the particle size. It is particularly applicable in the regime where the particle size is comparable to or smaller than the mean free path of the molecules in the fluid, which is often the case in rarefied gas dynamics.
