The sum of k i and ki2 is so high relative to the rate of micromixing that A and B will not coexist. Thus the number of ordinary mass balance differential equations requiring integration can be reduced from five to four by defining the following composite variables ... 

In Section 5.6, Lagrangian micromixing models based on mixing environments were introduced. In terms of the joint composition PDF, nearly all such models can be expressed mathematically as a multi-peak delta function. The principal advantage of this type of model is the fact that the chemical source term is closed, and thus it is not necessary to integrate with respect to the joint composition PDF in order to evaluate the...

Examination of the same mannosylation was performed by using the integrated microfluidic and batch systems as described earlier for microfluidic a-sialylation by the N-acetylated imidate 15 [19]. The Comet X-01 micromixer utilized for this case has a channel width of 500 pm (Fig. 8.5) because the micromixing with IMM mixer... 

Then the simulation of real chemical engineering flows concerns a number of important difficulties beyond the pattern of turbulent flows. One of these complex problems concerns the description of viscosity however, this can be resolved using rheological equations. Another difficulty is the so-called micromixing problem, which must be characterized at the level considering the integration of a very little unit. 

Because pit) = , the right side of Eq. (141) is a double integral over both X and t, and this can be reconducted to a double-label formalism if the second label is regarded as distributing over residence times (Aris, 1989). Of course, one expects Eq. (141) to hold for any degree of micromixing if the intrinsic kinetics are first order, but this remains to be demonstrated. 

Micromixers have been developed for flows ranging from < 1 mL h up to 10 000 L h At the low flow range, only single elements of the micromixer are required. These are often used in integrated systems for credit card sized fluidic chips [65]. For flows > 1 L h microstructured mixers are used for process intensification in pilot- and conventional-scale applications [65].
