Abstract
In this study, reaction-induced boundary movements in a thin channel are investigated. Here, precipitation-dissolution reactions taking place at the boundaries of the channel resulting in boundary movements act as a precursor to the clogging process. The resulting problem is a coupled flow-reactive transport process in a time-dependent geometry. We propose an ALE-based method (ALE-arbitrary Lagrangian-Eulerian) to perform full 2D computations. We derive a 1D model that approximates the 2D solution by integrating over the thickness of the channel. The boundary movements lead in the limit to clogging when the flow gets choked for a given pressure gradient applied across the channel. Numerical tests of the full 2D model are consulted to confirm the theory.
