Enhanced Modeling of Back-Mixing in Chemical Reactor Networks

Chemical reactor networks (CRNs) enable simulations of combustion reactors with detailed chemical kinetics and strongly simplified flow structure. In this paper, the implementation of a reactor component with less idealized flow structure, namely axial dispersion, to the CRN software NetSMOKE is presented. It is shown exemplarily that different flow models can lead to strongly different results in species prediction. However, computational efficiency remains an issue for this reactor class, which is still to be solved.
