AbstractSprache
We introduce mathematical models for a shrinking-core process in a heterogeneous reaction-diffusion system. The first model refers to diffusive mass transport. For this case a novel numerical approach is presented, allowing for calculation of the moving boundary as an explicit system variable. To cover the additional effect of migration which is present in our experimental set-up, the model is modified to incorporate electrical forces. Both models are compared and experimentally validated.Englisch
