A Chemical Probe for Characterising Turbulent Micromixing

Abstract: Micromixing strongly affects the molecular-scale contact of chemical species in numerous chemical reactions. Understanding the mechanisms governing micromixing lets us explain the relationships between the turbulence structure and the selectivity of the reaction. The micromixing models in the literature for large Schmidt numbers (Sc∼1000) are of two sorts: stochastic models (principally the Curl model) and deterministic models (such as IEM and the “engulfment” model). These models are essentially based on phen… Show more

“…The intrinsic parameter characterizing the absolute magnitude of the reaction apparent kinetics is the micromixing time t m (the inverse of a mixing rate), which can be considered the key parameter of chemical reactor performance for rapid reactions. The mixing time can be related to the segregation index by using physical models [26][27][28][29].…”

“…1. The segregation index can be related further to the mixing time by using physical models Bourne, 1989, 1999;Fournier et al, 1996b;Durandal et al, 2006;Falk and Commenge, 2010). Section 2 presents in detail the iodideiodate method, which is used in the present study since it presents the best accuracy among other chemical probe methods (Durandal et al, 2006).…”
