Abstract
Continuous-flow stirred tank reactors (CSTR) are widely employed to elucida te the kinetics and dynamics of chemical reactions. Complete information re garding the spatial heterogeneity of micromixedness over the entire tank is essential for interpreting data and identifying the mixing effects. Theref ore, in this work, we quantitatively estimate the segregation indices in a CSTR on the basis of a unique parallel competing reaction scheme proposed b y Villermaux and co-workers. Experimental results indicate that the segrega tion index is a function of stirring rate as well as of the spatial locatio n, from which, the mixing times can he estimated. Unexpectedly, although en hancing the micromixedness over the entire tank, a higher stirring rate can not ensure a more uniform medium.
