Estimation of the micromixing time in the torus reactor by the application of the incorporation model

• The incorporation model has been used to determine the micromixing time.
• The local energy dissipation rate has been determined from Kolmogorov's turbulence theory.
• The performances of the torus reactor have been compared to those of other devices.
• A correlation was established between micromixing time and micromixedness ratio.

On the basis of previous experimental results in a torus reactor, micromixing time is determined using the incorporation model. Obtained results allowed the characterisation of the performances of this new configuration of reactor in comparison to other reactors, such as the stirred tank reactor. In addition, a correlation is proposed for each incorporation law, in order to determine the micromixing time from the experimental micromixedness ratio (α). Finally, in terms of Kolmogorov's turbulence theory, a relationship between micromixing time and the local energy dissipation rate is obtained and compared to those previously published.
