  • Measurement of temperature in the low-temperature oxidation of fuels using two-tone nearinfrared absorption spectroscopy

説明

<p>A temperature measurement method based on laser absorption spectroscopy was developed to obtain the time history of temperatures during the low-temperature oxidation (LTO) of iso-octane. The absorption signals of H2O were measured using two near-infrared distributed feedback laser diodes emitting at wavelengths near 1392 and 1842 nm. The temperature was obtained based on the absorbance ratios between two temperature-dependent absorption lines. The temperature profiles in the LTO of iso-octane at 0.77 MPa, 660 K were successfully obtained. The calculated temperature profiles using the latest chemical kinetic model of iso-octane had the same tendency as the experimental profiles.</p>
