Scaling of the lateral permeability needed to match Goldsmith’s data with the number of channels.

The lateral permeability, s, and the corresponding effective diffusion constant needed to match Goldsmith’s data, for various values of n, the number of channels. The models are sketched in Fig 6. The last column shows the values of Deff expected from scaling by n2. For the first three values of s, i.e. for n = 2,6,21, the term 1/(ws) dominates 1/D in Eq (15), and one sees approximate quadratic scaling of s.Scaling of the lateral permeability needed to match Goldsmith’s data with the number of channels.
