RAYLEIGH SCATTERING AS A HIGH TEMPERATURE COMBUSTION DIAGNOSTIC METHOD

THIS PROJECT EVALUATES THE USE OF RAYLEIGH SCATTERING TECHNIQUES FOR USE AS A TEMPERATURE MONITOR IN THE SEVERE ENVIRONMENT OF GAS TURBINES. POTENTIAL ADVANTAGES OF THIS TECHNIQUE OVER ALL OTHER PRESENTLY USED METHODS ARE HIGH ACCURACY (+/-10K), EASE OF INSTALLATION, HIGH SPATIAL AND TEMPORAL RESOLUTION, AND NONINTRUSIVE OPERATION. THIS PHASEOF THE PROGRAM CONSISTS OF DETAILED FEASIBILITY CALCULATIONSAND THE DESIGN OF THE OPTICAL AND MECHANICAL COMPONENTS FOR A HIGH TEMPERATURE GAS MONITOR. MODELING CALCULATIONS UTILIZE EXISTING COMPUTER CODES TO DETERMINE THE SYSTEM'S SENSITIVITY, OPERATING RANGE AND OPTIMUM CONFIGURATION. THESE RESULTS LEAD TO FABRICATION, CALIBRATION, AND DEMONSTRATION OF THE TEMPERATURE MONITORING DEVICE IN THE PHASE II PROGRAM.
