N.I. Rodchenkova, Yu.V. Zaika. Numerical modeling of hydrogen desorption from cylindrical surface // Transactions of Karelian Research Centre of Russian Academy of Science. No 3. Mathematical Modeling and Information Technologies. 2010. Pp. 72-82

Keywords: hydrogen thermodesorption, mathematical modelling

Degassing of a cylindrical sample containing dissolved hydrogen is considered. The experiment is made by the thermodesorption method. In the corresponding boundaryvalue problem with nonlinear dynamic boundary conditions physical-chemical processes in the bulk and on the metal surface are taken into account: diffusion, desorption, capture by defects, and solution. Computational algorithm for desorption flux modelling is developed on the basis of difference approximations. The results of numerical modelling are presented. This work was supported by the Russian Foundation for Basic Research(grant 09-01-00439) and by the Russian Science Support Foundation.
