| 摘 要： | 文章采用蒙特卡罗法建立了红外灯单灯热流分布模型并在真空低温环境下进行了红外灯热流分布测试,以验证模型的准确性.测试在km2空间环境模拟器中进行,采用黑片作为热流传感器.测试过程避免了空气对流对测试的影响,确保了测试数据的准确.对比分析表明,模型计算结果与实测结果偏差在5%以内,满足设计要求,可以作为红外灯阵热流分布模型的建立和红外灯阵热流优化的基础.

| Abstract: | Monte Carlo simulation is used for predicting the radiant heat flux distribution produced by an infrared lamp. To obtain the corresponding empirical heat flux distributions for correlating with analysis, experiments were conducted in KM2 with radiometers, at a low temperature of 100 K and a vacuum environment of 1.3×10-3 Pa, to avoid the influence of air convection. The results show that the difference between the experimental and simulated results is less than 5%, and the simulation results can be used as a basis in the infrared lamp array optimization design. |
