The influence of H2O upon the precision of determining temperature and partial pressure of CO2 in diagnostics of CO2 : N-2 : H2O mixture with tunable CO2-laser

Abstract : The technique which makes it possible to simultaneously determine the temperature T and the partial pressure of carbon dioxide in a vibrationally equilibrium gas mixture at atmospheric pressure by using the spectral distribution of the unsaturated absorption coefficient at the oscillation lines of a tunable CO2 laser is presented. The results of model calculations of the influence of H2O molecules upon the precision of determining temperature and partial pressure of CO2 in CO2:N-2:H2O=10:80:10 mixture at full pressure 1 atm and temperature T=1000 K have given.
