Modeling Combustion with Detailed Chemistry

Zhuyin Ren Ph.D.Cornell UniversitySibley School of Mechanical & Aerospace EngineeringAbstractCombustion modeling is now playing an important role in the design and optimization of
advanced combustion devices such as internal combustion engines and gas turbine
combustors. For high-fidelity combustion modeling, it is essential, though challenging, to
resolve the highly nonlinear turbulence-chemistry interaction and to predict the emissions
of pollutants such as NOx and particulates. This requires the accurate description of
turbulent mixing as well as the use of detailed chemistry.In this talk, recent progresses in PDF methods for turbulent reactive flows, particularly
the sensitivity analysis, will be described and demonstrated. Then the talk will focus on
presenting the ICE-PIC dimension-reduction method and the ISAT storage-retrieval
method for the efficient implementation of detailed chemistry in combustion modeling.
The theoretical basis, validation, and computational efficiency of these methods will be
described. This talk will also describe the x2f_mpi software for efficient chemistry
calculations in large-scale parallel simulations. It will conclude with a discussion on
applying the ICE-PIC, ISAT, x2f_mpi algorithms to incorporate detailed chemistry in
combustion simulations.
