Title An evaluation of the one-dimensional turbulence model: comparison with direct numerical simulation of CO/H2 jets with extinction and reignition
Date 2010
Description Abstract A variant of the One-Dimensional Turbulence (ODT) model formulated in an Eulerian reference frame is applied to a planar nonpre mixed turbulent jet flame and results from the model prediction are compared with DNS data. The model employed herein solves the full set of conservation equations for mass, momentum, energy, and species on a one-dimensional domain corresponding to the transverse jet direction. The effects of turbulent mixing are modeled via a stochastic process, while the full range of diffusive-reactive length and time scales are resolved directly on the one-dimensional domain. A detailed chemical mechanism consisting of 11 species and 21 reactions and mixture averaged transport is used in this study (consistent with DNS simulations). Comparisons between the model and DNS data in physical and state space are shown, including conditional statistics. Results indicate that the model accurately reproduces the DNS data set. Turbulence-chemistry interactions, including trends for extinction and re-ignition, are captured by the model. Differences observed between model prediction and data are the result of early excess extinction observed in the model. The reasons for the early extinction are discussed within the model context.
