Four environment model of mixing and chemical reaction. Part II. Comparison with experiments

The four environment model, which was developed in Part I, has been compared with three extensive sets of experimental data from plug-flow and stirred-tank reactors with unmixed feedstreams and a single chemical reaction. The data sets have been accurately reproduced with a single value of the micromixing parameter (RS), and the “best fit” value of RS for each data set was close to the value estimated from the Corrsin-Rosensweig turbulent mixing theory. This lends support to the turbulence analogy suggested in Part I. Simulations of competing reactions of the parallel-consecutive type are used to discriminate between the four and three environment models with the four environment model providing much more realistic predictions.
