Flame Temperature Measurements by Time-domain Based Supercontinuum Absorption Spectroscopy

Abstract: Temperature is one of the scalar quantities of major interest in most technical combustion systems such as gas turbines, furnaces or internal combustion engines. In this work, we present for the first time quantitative temperature measurements in a flame by time-domain based supercontinuum absorption spectroscopy. In a 1-dimensional McKenna type burner temperature is inferred from broadband H 2 O spectra by a multi-peak least-square algorithm to data from the Barber-Tennyson line list (BT2) within a spectral r… Show more

“…On the stage of one of the most dynamic disciplines of spectroscopy, the advent of supercontinuum (SC) sources drastically marked the start of an epochal era with this technology mapped out across diverse scientific fields. An important development has been the emergence of SC generation, a condition where high-intensity pulses of light are propagated through the linear optical media in order to produce a wide spectrum of light which has been a major factor in going beyond normal spectroscopic impediments leading to enhanced sensitivity and resolution in analysis of various materials, biological entities, and atmosphere composition [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Moreover, it has become an integral part of modern spectroscopy in many ways by providing a very useful platform for the broadband light provision and this is key in the development and application of spectroscopic techniques [19][20][21][22][23][24][25][26][27].…”
