Formatted abstract
An FTIR-based spectroscopic technique is described that exploits silicon's transmissivity in the IR to make nonintrusive measurements of species concentration and temperature profiles in microcombustors. Species concentration is determined from the integrated absorbance (Beer's law), whereas gas temperature is determined by fitting a narrow-band spectral model (EM2C) to CO2 absorption spectra. The technique is demonstrated in a millimeter-scale combustor burning a lean ( = 0.86) CH4-air mixture. The results show that accuracies of 0.25 e-3 mol/L and 100C with spatial resolution 1 mm are possible. Heat fluxes to the wall are also estimated and thermal losses are found to be very high (90%).
