Cunningham correction factor formula
Web(1) is valid for values of the Reynold's number less than 0.5 (Stokes1 regime) (1). The slip correction factor C(DS) (sometimes called the Cunningham cor- rection) is an empirical factor which corrects Stokes1 law for discontinuities when the mean free path (X) of the fluid medium is comparable to the particle diameter. WebJan 1, 1989 · The existence of 'slip' at the periphery of these particles was realized later by Cunningham (1910). His proposal of a slip correction factor, C(Kn) for Stokes' Law was C(Kn) = 1 + A(Kn)Kn, (1) where Kn is the Knudsen number (Kn = 2/R, 2 being the mean free path of the molecules, and R the radius of the sphere) and A, a constant.
