    Abstract
  • A monodisperse model was introduced to simulate the TiO2 nanoparticles synthesization during the gas phase explosion.The calculation of this model was based on the experimental results and CJ theory which describes the gas phase explosion field.After a numerical analysis and theoretical explanation, the model was validated in comparison with the experimental results of gas phase explosion synthesis of TiO2.TiO2 nanoparticles with diameter of 20-150 nm were obtained.The results show that the numerical analysis can give a rapid predictive result of TiO2 nanoparticles synthesis, and the main factors affecting the growth of nanoparticles are reaction temperature, concentration of particles and reaction time.
