Numerical simulations of sonochemical production of BaTiO3 nanoparticles
چکیده انگلیسی

Numerical simulations of sonochemical production of nanoparticles have been performed for the first time under the experimental condition of Dang et al. [Jpn. J. Appl. Phys. 48 (2009) 09KC02] on the production of BaTiO3. The results of the numerical simulations have suggested that only primary particles aggregate with other particles. It is also shown that larger aggregates are produced for lower initial concentration of BaCl2 and TiCl4. This is caused by longer reaction time as the reaction rate is lower for lower concentration and by lower viscosity which results in higher rate of aggregation.


► We model sonochemical production of BaTiO3 nanoparticles.
► Numerical simulations were performed under the experimental condition of Dang et al.
► It is shown that only primary particles aggregate under ultrasound.
► Larger aggregates are formed for lower initial BaCl2 concentration.
