The Reconstruction of Two-Dimensional Distributions of Gas Concentration in the Flat Flame Based on Tunable Laser Absorption Spectroscopy
The experimental method by using the tunable diode laser absorption spectroscopy combined with the model and algorithm was studied to reconstruct the two-dimensional distribution of gas concentration. The feasibility of the reconstruction program was verified by numerical simulation. A diagnostic system consisting of 24 lasers was built for the measurement of H2O in the methane/air premixed flame. The two-dimensional distribution of H2O concentration in the flame was reconstructed, showing that the reconstruction results reflect the real two-dimensional distribution of H2O concentration in the flame. This diagnostic scheme provides a promising solution for combustion control.
