Abstract: A model to simulate the dissolution of multi-phase solid structures of arbitrary shape in multi-component fluids is developed. The dissolution reaction is supposed to be congruent and diffusion-controlled. The model uses a multi-component Lattice Boltzmann scheme in combination with a volume-tracking scheme for the moving interfaces. Equilibrium concentrations are imposed on the interfaces using an off-grid boundary condition. The resulting diffusion flux determines the dissolution rate. The model is applied to the dissolution of a laminar multi-phase solid in a diffusion boundary layer, and to a simplified three-component refractory-slag system.
