Boundary-value problem with moving bounds and dynamic boundary conditions: Diffusion peak of TDS-spectrum of dehydriding

In this paper, we present the boundary-value problem with moving bounds and dynamic boundary conditions that models the kinetics of hydrogen desorption from hydrides of metals. Phase change, desorption processes on the surface, size reduction, and heat absorption on the phase bound are taken into consideration. Computational algorithm based on difference approximations is developed. The results of numerical modeling are presented.
