IN SITU INFRARED DIAGNOSTICS IN A SILICON-WALLED MICROSCALE COMBUSTION REACTOR: INITIAL MEASUREMENTS

ABSTRACT

In situ infrared absorption measurements are performed through the walls of a silicon microcombustor to recover temperature and qualitative trends in major species concentrations as a function of streamwise distance through a partially premixed flame. This technique is shown to have promise for assessing combustion completeness and flame–structure interactions in microcombustors and for extending the boundaries of infrared spectroscopic techniques.
