The optical method for determining the thermodynamic parameters of hot gases

The research conducted on the thermodynamic parameters of a flame was based on its experimental transmission spectra in the 2.7μm and 4.3μm ranges. To produce the flame, alcohol was burned under atmospheric conditions. The hot gases resulting from the burning of ethanol (H2O, CO, and CO2) were accel...

Summary:The research conducted on the thermodynamic parameters of a flame was based on its experimental transmission spectra in the 2.7μm and 4.3μm ranges. To produce the flame, alcohol was burned under atmospheric conditions. The hot gases resulting from the burning of ethanol (H2O, CO, and CO2) were accelerated and spun by the rotation of an impeller. The optical method developed by the authors was employed for predicting the temperature and partial pressure of the hot gases. The results demonstrate the practical significance of the method suggested. The spectroscopic database HITEMP 2010 was used for all line-by-line calculations presented in the article. •We report an optical method for determining the thermodynamic parameters of hot gases.•This method was tested in an experiment by burning alcohol at surface level atmospheric pressure.•The results of this research indicate the practical application of the suggested method.
