摘　　要：为研究坦克排烟的红外辐射特性,建立了坦克排烟热流场数值计算模型,对流场分布进行分析和计算,得到了排烟的温度场分布。使用谱带模型C-G近似法,计算出排烟的辐射亮度,并进行热图像仿真。通过CO2辐射亮度的计算值与实测值比较表明:该模型和方法能够得到较为准确的结果,可应用于坦克排烟的红外热图像仿真。In order to study infrared radiation characteristics of fume released from the tank, the numerical calculation model of flow field for tank fume is established, then the flow field distribution is analyzed and calculated, so the temperature field distribution is gained. The radiance of fume is worked out by using C-G approximate model of channel bands and the thermal image simulation is completed. The radiance of carbon dioxide is computed and compared with the test value. The result shows that the model and the method can be used in the application of the infrared thermal image simulation.
