ABSTRACT

In recent years it has been increasingly recognized that thermal radiation plays an important, if not dominant, role in modern high-temperature environments and that reliable predictions of combustion behavior is not possible without a sophisticated radiation model. In this article an account of modern spectral methods is presented for the prediction of radiative heat transfer rates within combustion media consisting of strongly nongray combustion gases as well as mildly nongray soot particles, and perhaps accompanied by larger scattering particles. Modern narrow band methods are discussed, such as the statistical narrow band model (SNB) and k-distribution method. Emphasis is given to state-of-the art global models, including the weighted-sum-of-gray-gases (WSGG) model, the spectral-line-based WSGG model (SLW), and the full-spectrum k-distribution method (FSK).
