Investigation of the Emission and Absorption Spectra of Water Vapor

Emission and absorption spectra of water vapor are measured and analyzed for temperatures 350–2500 K in the spectral range 0.57–25 μm. Based on the developed mathematical model of radiative transfer, the parameters of spectral transmission functions of Н2О vapors are obtained at different temperatures. Practical application of the obtained radiative characteristics is considered for solving problems of radiative heat exchange in high-temperature media and designing optoelectronic systems intended for monitoring of aero carriers.
