Hybrid LES-multizonal modelling of the uranium oxalate precipitation

► Modelling of the uranium oxalate precipitation in an unbaffled reactor. ► The hydrodynamic model is based on the LES approach. ► The population balance is solved with the moment method in a multizonal model. ► One-way coupling between the multizonal and LES models. ► Simulations show a strong influence of feeding point as crystal sizes vary 8 times.
