Abstract
The Lifshitz-Slyozov (LS) and the Lifshitz-Slyozov-Wagner (LSW) models for the so-called "Ostwald ripening"are compared, with the purpose to test the limits of validity of the approximation that the LSW model is expected to represent for the LS model. The generally nonmonotonic behavior of the monomers' concentration is discussed and shown in a few examples. An asymptotic approach is followed to justify theoretically the aforementioned approximation. Illustrative examples are given.File in questo prodotto:
