摘要: First measurements of the adiabatic laminar burning velocities lean ethanol + oxygen carbon dioxide flames, at 1 atm and initial gas mixture temperatures 298, 318, 338 K, are presented. The content O-2/(O-2 CO2) in artificial air was 35%. were determined using heat flux method, where a non-stretched flame is stabilized under conditions. found qualitative agreement with modeling performed Marinov model, San Diego model by Leplat et al. In comparison to experimental data, gave best quantitative Notable differences between models analyzed sensitivity analysis reaction path diagrams. Reaction showed that have same 12 most important species. Among species al., 10 common other two models. According predictions combustion oxy-fuel conditions proceeds via path; however, sensitivities key reactions different. (Less)
