Low Vacuum as a Ground Simulation Method for Studies of Gas Convection Heat Transfer inside Manned Spacecraft.

为研究相应的模拟实验方法并建立载人航天器内部环境的地面模拟实验装置，克服地面上模拟微重力下气体对流散热的困难，本文提出在地面以低真空技术减弱自然对流模拟载人航天器内部对流散热的实验方法，建立合适的试验舱和采用合适的实验方法。

Owing to reduced gravity on the orbit, the convection model of the environment inside the manned spacecraft becomes complicated, and it is difficult to simulate under 1G condition for related sutdies on the ground. The author described a method using low vacuum to simulate the effect of reduced gravity on gas convection heat transfer for ground studies of environmental control and lifesupport system of manned spacecraft. It is demonstrated that when suitable experimental vessel and appropriate method are used,it is possible that convection heat transfer of the environment inside the manned spacecraft flying on the orbit may be simulated successfully on the ground.
