Abstract

A mathematical model was applied to the experimental data for the crystallization process from aqueous supersaturated cupric sulphate solutions in a batch isothermal stirred tank. The primary and secondary nucleation rate constants were obtained, and the dimensionless factors calculated from the primary and secondary nucleation rate constants were correlated with the impeller Reynolds numbers and the absolute temperatures. The secondary nucleation process, accompanied by crystal growth, was observed to be analogous to the population explosion in demography. In effect, this study offers a mathematical model for analysing the population explosion in ecology.
