N.I. Rodchenkova, E.K. Kostikova. Difference scheme for the boundary-value problem of hydrogen permeability in the presence of protective coating defect // Transactions of Karelian Research Centre of Russian Academy of Science. No 5. Mathematical Modeling and Information Technologies. 2011. Pp. 97-102
Keywords: hydrogen permeability, nonlinear boundary-value problems, difference schemes.
We consider the permeability of cylindrical barrier to hydrogen in the presence of protective coating defect on the inlet surface. For different structural materials, when diffusion and desorption are the limiting processes, corresponding mathematical models in the form of boundary-value problems with first-type conditions and nonlinear dynamic boundary conditions are presented. The difference scheme for numerical modelling of the permeation flux has been developed.
