Li, Qianqian published the artcileExperimental and kinetic modeling study of laminar flame characteristics of higher mixed alcohols, Recommanded Product: n-Octanol, the main research area is higher mixed alc laminar flame kinetic model.
Mixturesof alcs.combining strengths of lower and higher alcs.show promising alternative properties as engine fuel. To aid the extensive application of the mixed alcs., detailed combustion investigation is necessary. In this study, laminar flame speeds and Markstein lengths were measured for simplified higher mixed alcs.(blends of methanol and n-hexanol/n-heptanol/n-octanol) with spherically propagating flame at 0.1 MPa, elevated temperatureof 433 K, and different mixing ratios. A comprehensive model was developed to describe the high temperaturechem.of the mixed alcs. The accuracy of the model was validated with present data. Results reveal that the three higher alcs.exhibited close laminar flame speeds and Markstein lengths resulting from their similar thermal, diffusion, and chem.kinetic properties. With the increasing mixing ratio of the higher alcs., the laminar flame speed decreased, especiallyfor the rich mixtures The maximum laminar flame speed slightly shifted to the lean side. The Markstein length increased at extremely lean mixturesand decreased at extremely rich mixtures, with the intersection occurring at the equivalence ratio between 1.2 and 1.3. The laminar flame speed variation of the mixed alcs.was dominated by chem. kinetics. Reaction pathway analyses indicated that the cracking process of each component in the mixed alcs.remains as that in the pure alcs. Such result demonstrated the chem.kinetic effect resulting from changes in fuel components.
