Abstract
In draft tube (DT) crystallizers secondary nuclei originate predominantly from collisions between crystals and the impeller. The formation step of these nuclei is a complex process depending on the attrition behavior of the crystalline material and the two-phase flow pattern in the vicinity of the impeller. In order to develop crystallizer models with a predictive value for different operational conditions or for different scales of operation a mechanistic description of the secondary nucleation rate is a prerequisite. In this paper the predictive capability of a mechanistic model framework was studied by comparing the dynamic trend of the predicted median crystal size L 50 with the experimentally obtained one. The model is in good agreement with the experimental data regarding the predicted steady-state L 50 and the amplitude of the start-up oscillation. The dynamic behavior predicted by the model, however, differs from the measured one regarding the oscillation frequency and phase for reasons that will be addressed in the future.
