Yu.V. Zaika, E.K. Kostikova. Modeling of hydrogen permeability through protective coating defect // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Mathematical Modeling and Information Technologies. Vol. 3. 2012. Pp. 22-32

Keywords: hydrogen permeability, boundary-value problems, difference schemes, numerical modelling.

We consider the hydrogen permeability of a cylindrical barrier with a protective coating defect at the inlet surface of the structural material. Diffusion is the limiting factor. The computing algorithm based on implicit difference scheme was developed for solving the corresponding boundary-value problem. Results of numerical modeling of the permeability flux are presented.
