| Abstract |
Experimental and theoretical investigations of NO and NO2 formation and destruction in turbulent hydrocarbon/air diffusion flames have been conducted. Experimental results are presented for turbulent diffusion flames of a round jet of propane in a coflowing mildly swirled, S = 0.3, stream of air. Substantial concentrations of nitrogen dioxide were measured and nitrogen dioxide appears to peak slightly on the fuel rich side of the nitric oxide maxima. Several mechanisms for the formation of nitrogen dioxide in combustion systems are examined and the experimental results are discussed with reference to these mechanisms. The governing partial differential equations are solved for the propane/air turbulent diffusion flame. The predicted results from this analytical model are compared with experiment; reasonable agreement is obtained. |
