Radiative heat transfer calculations in real gases

A general formulation for radiative heat transfercalculations is presented, based on integrated quantities such as total emissivities and absorptivities. The procedure is intended particularly for combustion chamber applications of varEing degree of complexity, the radiative active medium consisting of gases such as H20 and CO2 and of soot. First, some preliminary calculations are given for the often treated radiative equilibrium cases of plane parallel plates and infinite concentric cylinders. Then an example of a combustion chamber calculation is studied where the radiative heat transfer calculation is included in a system of partial differential equations describing momentum, hear and mass transfer with combustion
