Numerical Simulation of Permeation from Deposited Droplets: Model Expansion

Abstract

A previously published model of permeation from a droplet has been expanded. Effects of downstream mass transfer resistance and concentration dependence of the diffusion coefficient have been included. An attempt was made to fit experimental results for the permeation of di-iso-propyl-methyl- phosphonate (DIMP) through Neoprene and natural rubber. Simulated data do not reproduce the initial pronounced delay of experimental permeation. Furthermore, no rationale has been identified for the anomalous dependence of breakthrough time upon barrier thickness observed with several experimental systems.
