Investigation of a spectral formulation for radiative heat transfer in one-dimensional fires and combustion systems

The radiative heat transfer in variable concentration, non-isothermal and sooty combustion products is investigated with a correlated-k gas method and discrete ordinates technique for the solution of equation of transfer. The spectrally formulated model is an approach for predicting radiative intensities and fluxes in mixtures of gaseous products (H2O, CO2, CO) and scattering soot particles. The reliability of this approach for fire and combustion applications is analysed by comparing its predictions with some theoretical results and measured radiative intensities for a natural gas flame. Use of this model for more accurate calculations and evaluation of simplified fire and combustion radiation models, are among its main advantages.
