Lamellar Mixing Simulation Using the Engulfment Model

5 Lamellar Mixing Simulation Using the Engulfment Model 

Bourne (1983) realized the important effect of the mixing process on the yield and product distribution of series-parallel chemical reactions. He and co-workers used the first Bourne reaction, described in Section 13-2.5, to do experimental studies of the effects of mixing on yield. They made extensive use of this reaction system (Bourne et al., 1981 Bourne and Rohani, 1983 Angst et al., 1984 Bourne and Dell Ava, 1987) and used the results to determine parameters in their models. 

Alkaline hydrolysis of nitromethane was used by Klein et al. (1980). These results were used to determine the parameters in the interaction and exchange with mean (lEM) model of Villermaux and Zoulalian (1969), which uses the balance equation for component j in the injection region for component i  

Equation (13-38) was combined with the equation for the engulftnent model to give the rate of change of the concentration of any of the reactants or products  

The model is similar to the interaction and exchange with the mean model, but the engulfment rate and the fraction B-rich fluid in the reaction zone determine the interaction rate, that is, 1 = E(1 — Xb).
