Absorption coefficient data for water vapor, carbon dioxide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and soot (carbon particles) are included in the program data statements. Provision has been made for the future addition of one additional radiating species. Input for the program is gas property data (temperature, pressure, and constituent mole fractions) in either an axisymmetric or three-dimensional cylindrical coordinate system. The program can integrate the radiation from the gas to a point to provide overall radiation as well as spectral distribution of radiation at intervals of 1/25 cm. In addition, detailed optical data can be provided at each spectral interval when only a single line of sight through the gas is considered. (Author) 收起
