Abstract
A procedure to optimize the radiative property calculations of gas-mixtures using the exponential wide band model (EWBM) is described in this paper. The procedure is applicable to any nitrogen-gas mixtures containing H 2O, CO 2, CH 4, CO, S0 2, NO, C 2H 2, N 2O and NH 3. The use of this procedure in calculating the total emissivity of H 2OCO 2 mixtures yields computational times comparable to those required by conventional emissivity correlations. The generality of the EWBM, along with minimized computational requirements, makes the procedure very attractive for incorporation into CFD codes for flame calculations. The coupling of the EWBM with classical solution methods of the RTE is discussed.
