^a Significant figures are shown unedited from the original sources.

^b Number of eigenvalues in the solution for ψ(ξ, τ) required to meet the criterion for the initial relative concentration of species A at the enclosure’s outer surface specified in the third column (Case 1 only). The initial concentration of A across the enclosure is set to zero in the diffusion model.
