Overview of Tests
The velocity measurements were performed with two-component fiber-optic laser Doppler anemometer (Dantec). All the details of the flow field measuring techniques applied in Sandia Flame D experiment are explained in[1]. Measured scalars for Sandia D Flame include temperature, mixture fraction, N2, O2, H2O, H2, CH4, CO, CO2, OH and NO. Experimental methods and measurement uncertainties are outlined in[1] Spontaneous Raman scattering of the beams from two Nd:YAG lasers (532 nm) was used to measure concentrations of the major species. The Rayleigh scattering signal was converted to temperature using a species-weighted scattering cross section, based on the Raman measurements. Linear laser-induced fluorescence (LIF) was used to measure OH and NO, and the fluorescence signals were corrected on a shot-to-shot basis for variations in Boltzmann fraction and collisional quenching rate. The concentration of CO was measured by Raman scattering and by two-photon laser-induced fluorescence (TPLIF).
