Simultaneous measurements of fuel vapor concentration and temperature in a flash‐boiling propane jet using laser‐induced gratings

“…To determine propane concentrations, the ratios of the amplitudes of the first two oscillation peaks of the LIG signals with clearly defined interfering electrostrictive and thermal contributions, R, have been employed, in much the same manner as it had been performed in the previous studies. [13,14] This approach resembles the one proposed and applied earlier in Ref. [29] The results of the calibration measurements of R(x) performed in this work in propane/nitrogen mixtures with four well-specified concentrations at temperature 294 K were found to be compatible, within the experimental errors, with the dependence obtained at 298 K in Refs.…”

“…Further references to the numerous applications of the LIG technique can be found in review articles. [33] The present work continues the previous studies, [13,14] where the process of injection of pressurized gaseous propane, C 3 H 8 , was investigated employing LIGs. Here, we demonstrate that the LIG technique is capable of performing simultaneous and quantitative measurements of the local gas phase temperature and fuel vapor concentration during the DI of a liquid fuel and evaporation process.…”

“…The experimental setup used for the studies of the pressurized fuel injection process employing LIG is similar to that described in detail in Refs. [13,14] The scheme of its optical arrangement for the LIG measurements is presented in Fig. 1.…”

“…the linear Raman spectroscopy (LRS), [8][9][10] the LIF techniques, [11,12] and the laserinduced grating (LIG) technique. [13,14] Nevertheless, a simultaneous measurement of both parameters is desirable, e.g. to guaranty the ignitability of the fuel/air mixture at all engine operation conditions.…”

Recent advances in linear and nonlinear Raman spectroscopy. Part IV

“…An editorial overview introducing the July 2009 special issue of the JRS on the European Conference on Nonlinear Optical Spectroscopy (ECONOS 2008) was given by Editor-in-Chief Wolfgang Kiefer. [325] A more technical and detailed introduction to this special issue on new topics and recent advances in coherent Raman microscopy and nonlinear optical spectroscopy was published by four Guest Editors, Andreas Volkmer, Peter Radi, Aleksei Zheltikov, and Andreas Zumbusch. [326] A book review titled 'Raman and SERS Investigations of Pharmaceuticals' by Monica Baia, Simion Astilean, and Traian Iliescu was published by Pinzaru.…”
