A new model is derived to establish the effective nucleation rate in terms of the MSMPR‐theory. The model is based on the concept of two‐step crystal growth, secondary nucleation, nuclei activation and metastable supersaturation. A comparison between model prdictions and experimental data from different crystallizers is presented. This model, which integrates hydrodynamics directly into its theory, proves to be extremely suitable for describing the MSMPR‐crystallization process.
