Pore-scale modelling of ostwald ripening
WebJul 21, 2024 · The Ostwald ripening regime induces a typical root-function dependence, known from the established literature 7, 8, confirming the validity of the model. The linear growth of mean particle size, observed in the particle agglomeration regime, on the other hand, could not be found in literature and represents a new insight into the mechanism of … Web2024. TLDR. The kinetics of Ostwald ripening of solid domains in the liquid phase of one-component systems in two dimensions is investigated numerically via the phase field crystal model, showing that dynamical scaling is reached during late times, and the growth law is in good agreement with the classical theory of Lifshitz, Slyozov, and Wagner.
