ANALYSIS OF RADIANT ENERGY EMISSION FROM HIGH-TEMPERATURE MEDIUM WITH SCATTERING AND ABSORBING PARTICLES

The paper presents the successive approximation method for solving the inverse problems of radiative transport. The conditions for unambiguous solutions as well as the estimates of convergence of the successive approximation procedure for planar, cylindrical and spherical systems are considered. The error estimates for selecting a suitable approach for solving the inverse problem and for calculation of the measurement errors for use of some approximate solution are suggested. Some cases of successfully employing the first order approximation for media with particles of combustion products have been presented. A technique for determination of the particle's temperature and the emissive ability of homogeneous scattering media has been advanced. The approximate relationships for the spectral dependencies of the single-scattering albedo and the asymmetry factor for the particles of combustion products are proposed.
