低空环境中浮空器的热数值模拟与实验研究

浮空器在通信等领域有着广阔的应用前景。温度控制是浮空器应用中涉及的关键技术之一，因此有必要对浮空器进行热分析和实验研究。本文针对低空环境与平流层的不同，考虑太阳直接辐射、天空散射辐射、地表反射的太阳辐射、大气辐射、地表辐射以及外部对流换热等因素，建立了浮空器在地面的热分析理论模型，利用CFD软件对浮空器进行了热数值模拟，并初步进行了实验研究。通过数值模拟结果与实验数据的对比，证明了理论模型具有一定的合理性。本文也为研究浮空器升空过程提供了数学物理模型。

Thermal Simulation and Experiment for An Airship under Low Altitude Environment

Stratospheric airships have great application prospects for communication fields. Temperature control is one key technique for the application of airships,so it is very important to do some thermal analysis and experiments for them. A mathematical model for the radiation and heat transfer of an airship is set up under low altitude environment in this paper. With this model and the CFD software,the temperature change of the ballonet was simulated. An experiment is also introduced and discussed. According to ...
