摘要：

Two distinctly different mechanisms that lead to growth rate dispersion have been observed experimentally. One of the mechanisms involves an initial growth rate distribution among nuclei, while the other allows crystal growth rates to fluctuate. The model formulated in the present work includes both phenomena. Solutions to population balances in a continuous mixed-suspension, mixed-product removal continuous crystallizer and a constant-supersaturation batch crystallizer are obtained in terms of parameters characterizing the two mechanisms.
