Paper Abstract

Multichannel near-infrared (NIR) spectroscopy is used to investigate two-phase, reacting flows. The spectral range is 1.2 to 5.3 microns. The NIR emission produced by the combustion of prepressurized gas mixtures consisting of hydrogen/oxygen/helium and carbon monoxide/oxygen is recorded by linear, 96 element, InSb diode arrays. Maximum time resolution is 1 ms for a full spectrum. The method has the potential for time resolved species analysis of instationary combustion reactions at high pressures.
