Conference paper


In this work a finite-mode probability density function approach coupled with Computational Fluid Dynamics is discussed to study mixing controlled reactions. The governing equations of turbulent reacting flows are presented and eventually a case study is analyzed: turbulent precipitation of barium sulphate in a semi-batch Taylor-Couette reactor. The role of operating conditions on final crystal size distribution is investigated and explained. Results show that precipitation is influenced by phenomena at all scales. However, it seems that under certain conditions micro-scale mixing can be neglected whereas macro- and meso-scale mixing should never be neglected.
