Diffusion in multiple laminates

Abstract

By a development of the method of Frisch a general treatment has been given of the time lag for diffusion in a multiple laminate ABCD... where each lamina is composed of a different material. The treatment relates to flow of heat or matter in laminated slabs, hollow cylinders or spherical shells, under conditions where the diffusion coefficients are independent of concentration in each lamina, and where Henry's law governs the distribution of diffusant between each pair of laminae. Several special cases have been treated numerically which demonstrate some properties of the time lag in laminates.
