In-Situ Measurements of Gas Species Concentrations in Simulated Dump Combustor Flowfields.
Abstract
A sampling probe-mass spectrometer system was assembled, calibrated and operated for making in-situ measurements of the concentrations of gaseous species in a combustor flow field. A series of tests were conducted in order to determine suitable design parameters for the gas inlet system and to determine the optimum operating conditions for the mass spectrometer. The accuracy of the mass spectrometric technique was verified over a wide range of concentrations through the analysis of gas mixtures with known compositions. In addition to the development of the gas sampling capability of the system constructed in the present research, this apparatus was interfaced to a computer in order to allow high-speed data acquisition and to facilitate data reduction. After the initial design and development phase, the mass spectrometric sampling system was used on a routine basis for the analysis of gas sampled from a simulated dump combustor flow field. Fuel (argon)/air mixing profiles were obtained for various test configurations and flow field conditions. The results of these tests illustrate the applicability of the gas sampling and analysis system to the in-situ measurement of gas species concentrations in high-pressure, ducted flow fields. (Author)
