CALCULATION OF RADIANT-HEAT EXCHANGE IN VOLUMES OF ARBITRARY GEOMETRY

A numerical method of calculating the divergence of the integral radia nt flux in terms of the spectral atomic lines based on the use of gene ralized group statistical models is presented. The proposed method is illustrated using as an example the solution of the radiative heat exc hange problem in an air plasma produced by a continuous optical discha rge. The influence of the atomic lines on hear exchange by means of se lective radiation is analyzed.
