The discrete-ordinates method is a simple, accurate and of little computational time solution to predict the radiative heat transfer in the combustion chambers. In this paperl three-dimension radiative problems for absorbing-emitting-scattering medium are modeled using this method in the rectangular enclosure. And in addition, new discrete-ordinates are developed to study the absorbing-emitting-scattering radiation processes for complex phase function. The reasonable results can be obtained through these new ordinates, yet the deviated results are only obtained through conventional Sn ordinates. 展开更多
