TY  - JOUR
AB  - In this paper, we present a methodology for simulating nanoparticle formation in a turbulent flow by coupling Direct Numerical Simulation (DNS) and population balance modelling.   The population balance equation  (PBE)  is solved via a discretisation method employing a composite grid that provides sufficient detail over the wide range of particle sizes reached during the precipitation process.  The coupled DNS/PBE approach captures accurately the strong interaction between the dynamics of turbulent mixing and particle formation processes.   It also allows  the calculation of  the  particle size  distribution  (PSD)  of the product and  enables an investigation on how it  is controlled by turbulent mixing.  Finally, it provides the statistics of kinetic processes and their timescales so that further analysis can be performed.  The methodology is applied to the simulation of experiments of hydrodynamics and nanoparticle precipitation in a T-mixer (Schwertfirm et al.,  2007,  Int. J. of Heat and Fluid Flow 28, pp.  1429-1442; Schwarzer et al., 2006, Chem.Eng.  Sci.  61, pp.  167-181), and the agreement with the experimental results is very good.
