Research output: Contribution to journalArticlepeer-review


The Zwietering maximum mixedness model (MMM) is extended for use with detailed chemical reaction mechanisms in a combustion setting. Both MMM species and energy balances are offered with a Chemkin-consistent nomenclature. The solution algorithm is discussed. Several reactor residence time distributions are currently offered for use with the MMM program. The MMM is used here to simulate observed literature species concentration data in a turbulent, jet-stirred combustor. For comparison, the results are also compared to simulations from perfectly stirred reactor (PSR) and partially stirred reactor (PaSR) models. The MMM model predicts the observed higher-than-PSR fuel conversions using a residence time distribution based on two unequal CSTRs-in series.
