Fundamentals of the spectral diagnostics of gases containing a condensed dispersed phase


Institute for High Energy Densities, Associated Institute for High Temperatures, Russian Academy of Sciences, Izhorskaya 13/19, Moscow, 127412, Russian Federation

The emission from a gas containing macroscopic particles, as well as the transmission of light through such a system with account taken of multiple scattering of light by the particles, is studied. The emission from objects of different shapes is studied in the continuum and in spectral lines. The influence of the scattering particles on this emission is studied theoretically and experimentally. The emission from a closed isothermal cavity filled with gas containing a condensed dispersed phase is analyzed. Relationships are obtained that are necessary to determine the temperature of the gas and the particles, and the concentration of atoms (or molecules) from the measured intensities of the intrinsic and transmitted radiation.
