| Abstract | Laminar flame speeds of three pentanol isomer (1-, 2-, and 3-pentanol)–air mixtures were measured at equivalence ratios of 0.6–1.8, initial pressures of 0.10–0.75 MPa, and initial temperatures of 393–473 K using the outwardly propagating spherical flame. A recently developed kinetic mechanism of 1-pentanol oxidation (Dagaut model) was used to simulate the laminar flame speeds of 1-pentanol–air mixtures under experimental conditions. A comparison between simulation and measurement shows that the simulation yields good agreement on the stoichiometric and fuel-rich side, but it gives lower values on the fuel-lean side. A kinetic modeling study was performed, and several rate constants of selected elemental reactions were modified on the basis of the sensitivity analysis. The modified model gives good prediction on the laminar flame speed under all experimental conditions. The modified model is also validated against the jet-stirred reactor (JSR) experimental data, and it exhibits good prediction for most spe... |
