摘要: Precipitation of nanoscaled particles and the size-determining precipitation parameters are investigated experimentally as well numerically using barium sulfate a reference substance. The objective this work is to successfully understand predict kinetics. Optimization tailoring product properties specific needs would then be possible without need extensive experimentation its costs. Special attention paid influences mixing stabilization on formed PSD. To simulate particle formation population balance equation, including terms for nucleation, growth, agglomeration, coupled with an specially developed extended version equi-volumetric Engulfment-Deformation-Diffusion-model micromixing Baldyga Bourne (1999). proposed predictive model nanoparticle explained in detail simulation results presented, discussed, compared experimental results.
