英文摘要	This paper investigates the effects of coflow O-2 level and temperature on diffusion flame of a CH4/H-2 jet in hot coflow (JHC) from a burner system similar to that of Dally et al. The coflow O-2 mass fraction (y(O2)) is varied from 3% to 80% and the temperature (T-cof) from 1200 K to 1700 K. The Eddy Dissipation Concept (EDC) model with detailed reaction mechanisms GRI-Mech 3.0 is used for all simulations. To validate the modeling, several JHC flames are predicted under the experimental conditions of Dally et al. [Proc. Combust. Inst., 29 (1), 1147-1154 (2002)] and the results obtained match well with the measurements. Results demonstrate that, when y(O2)* decreased, the diffusion combustion is likely to transform from traditional combustion to MILD (Moderate or Intense Low-oxygen Dilution) combustion mode. When T-cof* is higher, the temperature distribution over the whole domain trends to be more uniform. Reducing y(O2)* or T-cof* leads to less production of intermediate species OH and CO. It is worth noting that if y(O2)* is high enough (y(O2)* >80%), increasing y(O2)* does not cause obvious temperature increase.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000323644000013&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Engineering, Chemical; SCI(E); EI; 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 5; 7; 787-799; 21
