Formaldehyde is an important combustion intermediate, which is often used for the analysis of turbulent flames, internal combustion engines or droplet/spray ignition processes. Due to its high concentration in hydrocarbon fuel combustion, laser induc

Optical emission spectra of rich HMDSO/propane/air and propane/air flames (equivalence ratio Φ=1.33) were recorded using an imaging spectrometer in combination with an intensified CCD camera. The probe area was about 1×0.2 mm2. This is small for th

Formaldehyde is an excellent tracer for the early phase of ignition of hydrocarbon fuels and can be used, e.g., for characterization of single droplet ignition. However, due to its fast thermal decomposition at elevated temperatures and pressures, th
