Ripening with noise

Abstract

The process of ripening has been considered taking into account the noise from different sources, namely the scatter of compositions (supersaturation Δ) in the vicinity of precipitates and scatter of the Gibbs–Thompson term α. The evolution of the particle size distribution (PSD) has been investigated using parameters that characterize the width, sharpness and slope of the peak. Accounting for noise in our model produces a PSD that is closer to the experimental data compared with LSW theory.
