Title of the article | Mathematical modeling of corrosion mass transfer of the heterogeneous system «corrosive liquids – cement concrete». Special cases of the solutions |
Abstract. | Mass transfer corrosion of the second type of cement concrete is mathematically modeled in the present article. This specific kind of corrosion degradation, which occurs most often in industrial production, associated with release or use of acids. The boundary-value problem of mass condition is shown in the case of the wall of a concrete structure in chemical interaction with aggressive component of aquatic environment in dimensional and dimensionless variables. The final solution by Laplace method is presented for small values of mass transfer Fourier number. We describe two special cases of the solution: the equal distribution of the mass source according to the thickness of concrete, and in the case where the mass source is distributed along the coordinate. For each particular case calculation results in graphical form are given. Obtained during numerical simulation graphics are in good agreement with the physical picture of the process of mass transfer on the corrosion mechanism of the second kind. |
