Description
Summary:For the initial-boundary value problem of admixture diffusion in a two-phase multilayered bodywith the uniform distribution of phases the influence of errors on behaviour of the mass flow isinvestigated. The effect of input data errors, method and rounding errors on the averaged diffusionflow is analyzed. A series of numerical experiments are carried out. It is shown that the presenceof measurement departures in the initial concentration and characteristic thickness of inclusionshas the greatest effect on the flow disturbance and reduced diffusion coefficient disturbances leastinfluence on the flow.
