空间飞行器内结露的理论分析及模拟实验

目的 探讨防止载人空间飞行器舱内结露的方法 。方法 从热力学和传热学的角度分析和研究了空间飞行吕同的结露条件及过程，对影响舱内结露的几个因素进行了探讨。结果 壁面隔热有利于防止结露，局部通风有可能抑制结露。但单独采用隔热或通风的方法均存在一定的局限性，降低外壁黑度有利于防止舱内结露。结论 采用壁面隔热和局部通风相结合的方法。可以有效地达到防止结露的目的。

Theoretical Analysis and Simulation Study of Dewing in Spacecraft.

s: Objective To study the method of preventing dewing on the cabin wall of a spacecraft. Method Theoretical analysis and experimental study of the factors and process of dewing on the cabin wall in a spacecraft were carried out according to principles of thermodynamics and heat transfer.Several factors relating to dewing were discussed and evaluated. Result Thermal insulation could be used to prevent dewing on the wall.Ventilation might be beneficial for suppressing the dewing.Effects of these methods were limited if they were used singly.Decrease of the emmisivity of the outer surface of the wall was favorable for preventing dewing on the inner surface of the cabin wall. Conclusion Dewing on the wall could be prevented effectively by thermal insulation together with local ventilation.
