Experimental and Numerical Investigation of CH* and OH* Chemiluminescence in Acetylene Combustion behind Reflected Shock Waves
Spontaneous light radiation from chemical excited species is responsible for the well-known emission of flames. Blue light emission due to the CH(A2Δ-X2Π) and UV emission from the OH(A2Δ-X2Π) transitions are specific features in hydrocarbon combustion and are most frequently employed in various applications. The simplicity of the detection of the spontaneous emission compared to laser-based diagnostics make chemiluminescence spectroscopy very attractive for the investigation of flames and potentially for combustion control. This, however, requires a fundamental understanding of the coupling of light intensities and spectral features to the underlying chemical processes in a practical combustion situation.
