A reduction approach for coupling complex kinetics with engine computational fluid
dynamics (CFD) code has been developed. An on-the-fly reduction scheme was used to
reduce the reaction mechanism dynamically during the reactive flow calculation in
order to couple comprehensive chemistry with flow simulations in each computational
cell. KIVA-3V code is used as the CFD framework and CHEMKIN is employed to for-
mulate chemistry, hydrodynamics and transport. Mechanism reduction was achieved
by applying element flux analysis on-the-fly in the context of the multidimensional
CFD calculation. The results show that incorporating the on-the-fly reduction
approach in CFD code enables the simulation of ignition and combustion process
accurately compared with detailed simulations. Both species and time-dependant
information can be provided by the current model with significantly reduced CPU
time. VVC 2009 American Institute of Chemical Engineers AIChE J, 56: 13051314, 2010
