  The dynamics of solid-liquid interfaces controlled by solute precipitation
and/or dissolution due to the chemical reaction at the interface were computed
in two dimensions using a phase field models. Sharp-interface asymptotic
analysis demonstrated that the phase field solutions should converge to the
proper sharp-interface precipitation/dissolution limit. For the purpose of
comparison, the numerical solution of the sharp-interface model for solute
precipitation/dissolution was directly solved using a level set method. In
general, the phase field results are found in good agreement with the level set
results for all reaction rates and geometry configurations investigated.
Present study supports the applications of both methods to more complicated and
realistic reactive systems, including the nuclear waste release and mineral
precipitation and dissolution.
