| Outline of Final Research Achievements |
In order to achieve OH-Planar Laser-Induced Fluorescence (OH-PLIF) measurements to rocket combustion which emits intense chemiluminescence, OH(2,0) band excited OH-PLIF method was developed in this study. The OH(2,1) band fluorescence was detected effectively by eliminating the interference of intense OH(0,0) band chemiluminescence, and the images of two-dimensional instantaneous OH distribution in H2/O2 jet diffusion flames were successfully acquired up to 5.9 MPa. Moreover, a calibration burner capable of adapting to high pressure and temperature flame conditions was designed to establish the quantitative optical measurement methods for rocket combustion. The oxygen-enriched CH4/O2/N2 laminar quasi one-dimensional flames were stabilized on the burner up to 0.49 MPa, with maximum flame temperature simulated to be higher than 2900 K. From these results, the primal requirements of the calibration burner were sufficiently archived.
