| Outline of Final Research Achievements |
Rocket combustion is a representative combustion phenomena under an extreme condition because the orders of pressure and temperature are 10 MPa and 3000 K, respectively. Combustion measurement for such extreme condition is generally difficult using conventional laser diagnostics. In this study, it was succeeded quantitative temperature measurement of oxygen enriched methane/oxygen/nitrogen premixed flames up to 1.0 MPa using Laser Induced Thermal Grating Spectroscopy (LITGS) which is promising laser diagnostics available for high pressure combustion. In addition, it is suggested that the chromatic aberration of the crossing lens used in LITGS optics and laser intensity of the pump beam are important for the accuracy of temperature measurement using LITGS.
