摘要
利用离散坐标法对圆柱形炉膛辐射传热进行了计算,结果与计算精确的区域法的计算结果符合较好;同时又利用离散坐标法和热流法对旋流燃烧室温度场进行比较计算,结果表明:离散坐标法计算结果与文献中实验结果符合较好;离散坐标法具有较好计算精度,可应用旋流燃烧辐射计算中.
The discrete ordinate method is used to calculate the radiation heat transfer in a cylindrical shape furnace.The results of the discrete ordinate method are in good agreement with those of the zone method.Temperature profiles in a swirl combustor are simulated using the discrete ordinate method and the heat flux method,separately.The results show that the discrete ordinate method agrees well with the experimental data.The discrete ordinate method has better accuracy,which is applied to radiation computation in the swirl combustor.
