A moving boundary diffusion model for the corrosion of concrete wastewater systems: simulation and experimental validation

An experiment is constructed which provides data from which the efficacy of a moving boundary reaction-diffusion based model for the sulfide corrosion of concrete can be established. The model is derived and its finite dimensional approximation is discussed. A diffusion rate is identified using data supplied by the experiment. The results of the experiment and the comparison of experimental data with simulation studies based upon the model are discussed.
