在本文中，我们进行了三维数值研究，调查辐射传热的模型燃气涡轮机燃烧室，代表的罗尔斯-罗伊斯泰燃烧室。本文采用一般贴体坐标系下的离散坐标法（DOM/Sn）求解辐射传递方程（RTE），并结合大涡模拟（LES）对燃烧室内的流场、温度场和组分场进行了模拟。在这项工作中考虑的辐射是由于只有热的燃烧气体，特别是二氧化碳（CO2）和水蒸气（H2O），也被称为非发光辐射。计算了燃烧室内辐射特性的瞬时结果，如入射辐射和辐射能源或辐射能汇作为辐射热通量的发散，并以图形表示。
In this paper we have carried out a three-dimensional numerical study to investigate the radiative heat transfer in a model gas turbine combustor, representative of the Rolls-Royce Tay combustor. The Discrete Ordinate Method (DOM/Sn) in general body-fitted co-ordinate system is applied to solve the filtered Radiative Transfer Equation (RTE) for the radiation modelling and this has been combined with a Large Eddy Simulation (LES) of the flow, temperature and composition fields within the combustion chamber. The radiation considered in this work is due only to the hot combustion gases notably carbon dioxide (CO2) and water vapour (H2O) also known as non-luminous radiation. The instantaneous results of the radiation properties such as the incident radiation and the radiative energy source or sink as the divergence of the radiative heat fluxes are computed inside the combustion chamber and presented graphically.
