Abstract

An engineering technique for determining the thermodynamic parameters of a hightemperature gas volume is described on an example of water vapor The suggested approach consists in exact calculation of the attenuation of the intensity of several laser lines in the gas volume for fixed intervals of temperature and partial pressure with the subsequent approximation of the transmission function depending on the thermodynamic parameters of the medium The polynomial coefficients so obtained are then used to solve the inverse gas analysis problem for unknown partial pressures of gaseous components of the medium and its temperature The technique is suitable for simultaneous remote monitoring of the gas temperature from 400 to 1600 K and partial pressure from 0025 to 02 atm with an error no more than 10
