| Outline of Final Research Achievements |
General-purpose spectroscopic method using an incoherent light source was developed for the auto-ignition phenomena by using a rapid compression machine. The incoherent light source was applied to the flow observation in the reactor of rapid compression machine, and also spectrum observation. Visualization of fluid and measurement of temperatures distribution in the reactor were performed. As a result, it was found that the core-gas model was comparatively good approximation for analyzing rapid compression machine.
Also, the measurement of auto-ignition of basic paraffin fuel with aromatic hydrocarbons were carried out by using this machine. The reaction analysis by using detailed chemical kinetic model with core-gas model suggested that the initial temperature after compression by the piston was carefully estimated because the ignition delay time was very sensitive to the initial temperature of the reaction.
