Simulation of turbulent precipitation in a semi-batch Taylor-Couette reactor using CFD

A finite-mode probability density function method was used with a computati onal fluid dynamics cone to model the semibatch precipitation of barium sul fate from aqueous solutions of barium chloride and sodium sulfate in a Tayl or-Couette reactor: It was simulated in turbulent flow at high Taylor numbe rs under the assumption of axial symmetry. The flow field was modeled using two different turbulence model and flow predictions were validated using e xperimental tracer dispersion measurements. The crystal-size distribution ( CSD) was calculated in terms of the first five moments considering both nuc leation and growth, while neglecting the effect of aggregation. The effect of the operating conditions on the CSD was studied, and code predictions we re compared with experimental data.
