RT Journal Article ID 1fa780d45ced9465 A1 Taine, Jean A1 Soufiani, Anouar T1 Spectrally Correlated Radiative Transfer in Real 3D Axisymmetrical Systems (The Sc. Art Code) JF International Journal of Fluid Mechanics Research JO FMR YR 1998 FD 1998-06-01 VO 25 IS 1-3 SP 52 OP 63 AB A method for the treatment of radiative transfer in a general axisymmetrical system containing an absorbing, emitting but nonscattering mixture of gases and particles is presented. A Random Statistical Narrow Band method is used in order to model the radiative properties of gases (CO2, H2O ...). The spectral effects due to the correlations between the gas line positions for different column elements arc computed by using the Curds-Godson approach for some principal directions and approximated for the other directions by using a continuous correlation function. The correlated intensities are computed for each point and each narrow spectral band for a large number of directions which belong to planes parallel to the axis of the system. The general code reliable for any 3D axisymmetrical system, which may contain internal bodies, is validated in the cases of a planar geometry and an infinite cylinder by comparison with an exact direct numerical calculation. The correlation effects are discussed in different conditions. An example of application in a complex geometry is given.
