465606 “Validation of the Coalescence-Dispersion Model of Mixing for Complex Chemical Reactions”
Integration of the c-d model into a CFD simulation requires that the mobile fluid points move, mix and disperse in a way dictated by the CFD simulation. Each volume segment of the CFD simulation is assigned a number of fluid points which move from segment to segment as dictated by the CFD simulation. This is accomplished by a subroutine linked to the CFD code that accesses the velocity and mixing rate predictions of the CFD. A critical aspect of the c-d model is in the most effective choices of the time increment and the number of fluid points in each CFD volume segment. This is dependent on the number of c-d events during each time increment and the flow volumes from segment to segment.
The validations have been done by comparing results with well-established experimental data for single and multiple reactions in various types and sizes of chemical reactors. The validations show that the c-d simulation method can be a valuable addition to experimental research on multiple competitive reactions where there is interest in yields of given products.
