The Mathematical Modeling of Metals Mass Transfer in Three Layer Peat Blocks

Ērika Teirumnieka, Ilmārs Kangro, Edmunds Teirumnieks, Harijs Kalis

Abstract


The mathematical model for calculation of concentration of metals for 3 layers peat blocks is developed due to solving the 3-D boundary-value problem in multilayered domain-averaging and finite difference methods are considered. As an example, mathematical models for calculation of Fe and Ca concentrations have been analyzed.

Keywords


averaging method; finite difference method; boundary conditions of third type; heavy metals; peat bog
