Temperature Measurements in Polydisperse Sprays by Means of Laser-Induced Fluorescence (Lif) on Three Spectral Bands

Temperature and chemical composition of droplets by optical measurement techniques: a state-of-the-art review

“…Temperature measurements in sprays: Several studies have more specifically addressed the implementation of the 2cLIF technique in sprays (Bruchhausen et al 2006;Depredurand et al 2011;Labergue et al 2010Labergue et al , 2012aWolff et al 2007). These studies describe how the 2cLIF technique, initially used and validated in the case of single calibrated droplets, should be modified for reliable measurements in sprays.…”

High-pressure Diesel spray temperature measurements using two-colour laser-induced fluorescence

“…However, the influence on the signal of the first spectral band remains negligible, taking into consideration the accuracy of the spectrometer. (2) The wavelength-dependent scattering of the fluorescence emission may cause a shift of the spectrum, during the travel of the polychromatic fluorescence signal through the spray [10]. However, no shift between the reference spectrum and the spectra recorded in the spray can be observed (figure 9).…”
