Global Weak Solutions and Well-posedness of Weak Solutions for a Moving Boundary Problem for a Coupled System of Diiusion-reaction Equations Arising in the Corrosion-modeling of Concrete (part 2) Partially Supported by Dfg

چکیده
The evolution of the corrosion interface separating the uncorroded concrete part and the corroded part of a partially wet concrete wall of a pipe under the innuence of hydrogen sullde can be modelled by a moving boundary problem for three coupled one-dimensional diiusion equations. We show that the problem formulated via weak solutions is well-posed. The function describing the position of the moving boundary belongs to W 1;1 (IR +). The paper generalizes previous results by relaxing the assumptions and by providing global weak solutions instead of local ones.

Continuity with Respect to Data and Parameters of Weak Solutions to a Stefan-like Problem
We study a reaction-diffusion system with moving boundary describing a prototypical fast reaction-diffusion scenario arising in the chemical corrosion of concrete-based materials. We prove the continuity with respect to data and parameters of weak solutions to the resulting moving-boundary system of partial differential equations.

We deal with a one-dimensional coupled system of semi-linear reaction-diffusion equations in two a priori unknown moving phases driven by a non-local kinetic condition. The PDEs system models the penetration of gaseous CO2 in unsaturated cement-based porous materials (concrete). The main issue is that CO2 diffusion and fast reaction with Ca(OH)2 in concrete lead to a sudden drop of alkalinity n...

In this paper, three dimensional (3D) static and dynamic analysis of thick plates based on the Meshless Local Petrov-Galerkin (MLPG) is presented. Using the kinematics of a three-dimensional continuum, the local weak form of the equilibrium equations is derived. A weak formulation for the set of governing equations is transformed into local integral equations on local sub-domains by using a uni...
متن کاملError Bounds on Semi-discrete Finite Element Approximations of a Moving-boundary System Arising in Concrete Corrosion
Finite element approximations of positive weak solutions to a onephase unidimensional moving-boundary system with kinetic condition describing the penetration of a sharp-reaction interface in concrete are considered. A priori and a posteriori error estimates for the semi-discrete fields of active concentrations and for the position of the moving interface are obtained. The important feature of ...
