Some elements of radiative heat transfer calculations in flames and gases
Journal article, 1973
The validity of approximations in methods to be used in radiative heat flux calculations in flames and combustion gases is discussed. The principal problem is whether quantities such as emissivity and abrorptivity of gases and soot, defined for homogeneous media, may be employed alsoin media where temperature and concentration vary. Some examples are studied where the approximative methods are compared with resulrs from more refined calculations for carbon dioxide, water vapour and soot-gas mixtures.
