N2 - Particle deposition with simultaneous erosion of the deposit layer formed is a moving boundary problem found in many engineering applications. The present work presents a numerical model for particle deposition with simultaneous deposit erosion under a given flow condition. For accurate numerical modeling of these combined phenomena, fluid transport, particle transport, particle deposition, deposit erosion, interface transport are fully-coupled and hence need to be accounted for together. Particle deposition and shear stress induced deposit erosion are modeled respectively using a 1st order reaction and threshold erosion law. The interface between fluid and deposit regions is evolved through the level-set approach. The governing conservation equations for mass, momentum and species (particles) are discretized and solved by employing the finite volume method. The developed model is verified and then applied to study pure erosion of a erodible circular object and combined particle deposition and deposit erosion of a non-erodible circular object. The importance of including deposit erosion in the model is clearly demonstrated.
