A new unsteady mixing model to predict NO(x) production during rapidmixing in a dual-stage combustor

Mixing Characterization of Transient Puffs in a Rotary Kiln Incinerator

“…The most rigorous evaluation of linear eddy modeling predictions for reacting flows is by Kerstein (1992b), who compared simulation of reaction between NO and 0 3 in a shear layer to experimental data, at different Damk6hler number. Menon et al (1992) compared plots of temperature as a function of mixture fraction in hydrogen-air combustion, from linear eddy simulations and experimental data, and predicted the NO emission index in hydrogen-air combustion.…”

Unsteady methods (URANS and LES) for simulation of combustion systems

“…For reacting case, the reader may refer to [53,55]. To close the governing equations, a standard k-epsilon-model and a second-order closure (DSM) chosen for its well-known capability to well predict complex flows have been used.…”

“…Thus, the combustion process occurs essentially at the smallest scales of the sub-filter level, which has to be modeled in LES. As in averaged governing transport equations in URANStechniques [53,55], additional closure problems arise as well from combustion related terms in the filtered governing transport equations used in LES.…”

Linear eddy modeling of turbulent combustion

“…Below, some details of the model and its implementation are given. For more complete discussions, the reader is referred to the growing body of literature on this modeling approach (e.g., Kerstein, 1988Kerstein, ,1991Kerstein, ,1992McMurtry et al, 1993;Menon et al, 1993a).…”

“…3.2 Combustion Processes in Turbulent Jets. A further illustration of the ability of the model to treat different geometrical configurations plus the added complication of combustion is the application of the linear eddy model to turbulent jet flames (Kerstein, 1992; Menon et al, 1993a). In these two applications the linear eddy domain was taken to be a line down the axis of the jet.…”
