SIMILARITY PARAMETERS FOR RADIATIVE ENERGY TRANSFER IN ISOTHERMAL AND NON-ISOTHERMAL GAS MIXTURES

Abstract

The similarity groups for multicomponent, reacting gas mixtures with radiative energy transport are derived. The resulting relations are used to consider the feasibility of scaling for flow processes with radiative energy transport under highly simplified conditions. The scaling parameters are derived for radiant energy emission from isobaric and isothermal gases for arbitrary opacities and various spectral line and molecular band models. Scaling parameters for radiant energy emission from isobaric but non-isothermal systems are discussed for arbitrary opacities and various spectral line and molecular band models under the restrictions imposed on the allowed temperature profiles for dispersion and Doppler lines by the Eddington Barbier approximation. Finally, the radiative scaling properties for representative temperature profiles are considered for both collision broadened and Doppler-broadened line profiles on the basis of exact numerical calculations that were performed for a rotational spectral line be longing to a molecular vibration-rotation band.
