The eeects of chemistry and turbulence on NOformation in oxygen-natural turbulent diiusion ames gas ames have been investigated. The chemistry of nitric oxides has been studied numerically in the counterrow connguration. Systematic calculations with the GRI 2.11 mechanism for combustion of methane and NO chemistry were conducted to provide a base case. It(More)
Two t ypes of mixing sub-models are evaluated in connection with a joint-scalar probability density function method for turbulent nonpremixed combustion. Model calculations are made and compared to simulation results for homogeneously distributed methane-air reaction zones, mixing and reacting in decaying turbulence within a two-dimensional enclosed domain.(More)
Introduction In conventional energy conversion devices (e.g., gas turbines and piston engines) useful work is produced in a two-step process: conversion of chemical energy to sensible energy by combustion, followed by work extraction by expansion. The first of the two processes typically occurs on a very short time scale and is essentially complete before(More)
We have studied the reaction between CH and N2, (1) CH + N2 --> products, in shock tube experiments using CH and NCN laser absorption. CH was monitored by continuous-wave, narrow-line-width laser absorption at 431.1 nm. The overall rate coefficient of the CH + N2 reaction was measured between 1943 and 3543 K, in the 0.9-1.4 atm pressure range, using a CH(More)
