Population balance and computational fluid dynamics models were built and integrated for a simulation study of reactive crystallisation process in a confined jet mixer for continuous flow synthesis of TiO2 nanoparticles in supercritical water. The combined model of nanocrystal aggregation and surface growth was found to provide a more accurate prediction of particle size distribution compared to models that only consider surface growth as the mechanism for particle size enlargement.
Population balance and computational fluid dynamics models are built and integrated to carry out a simulation study of the reactive crystallisation process in a confined jet mixer (CJM) for the continuous flow synthesis of TiO2 nanoparticles at a supercritical water condition. In the population balance model, the crystal growth in size is modelled as being due to combined nanocrystal aggregation as well as surface growth. A free molecular model is used to predict the particle aggregation. The performance of the combined aggregation and surface growth models is compared with models that only consider surface growth as the only mechanism for particle size enlargement. It was found that the combined model gives a more accurate prediction of particle size distribution.
