In this contribution, the development of a compartmental model for the dynamic simulation of an 1100L DTB crystallizer is presented. Design of the compartment structure was based on high resolution CFD simulation of the internal flow of the crystallizer. The CFD simulation of the turbulent flow field was based on a lattice-Boltzmann scheme with a Smagorinsky subgrid-scale turbulence model (c(s) was 0.11), The fully developed turbulent flow field was simulated at Re=240.000 on 35.5 . 10(6) grid nodes. A detailed compartmental model with 21 compartments was derived. The model contained mass, heat and population balances for each compartment. From the CFD simulations, flow rates and local rates of energy dissipation fur each compartment were determined. Explorative simulation results of the compartmental model are presented to demonstrate the influence of compartment structure, short circuiting flow and late of energy dissipation on the evolving crystal size distribution.
