多孔材料因其特殊的结构,可以利用渗透作用在太空微重力条件下实现物质的输运和分离,因而在航天生保设备中广泛引用。传统的模拟仿真方法只能简单获得多孔介质内的流阻特性,无法模拟出因多孔结构造成的毛细作用、水气分布特性,限制了设计多孔材料的单机仿真研究工作的推进。本文介绍了用以研究微重力条件下多孔材料特性的模拟仿真研究进展,并在此基础上概括归纳了各研究方法的特点及适用范围。
Due to its special structure, porous materials can make use of osmosis to transport and separate materials under the conditions of space microgravity. Therefore, porous materials are widely used in aerospace environmental protection equipment. The traditional simulation methods can only get the flow resistance characteristics of porous media easily, and can not simulate the capillary action and moisture distribution caused by the porous structure, which limits the promotion of single machine simulation of porous materials design. In this paper, the progress of simulation research to study the properties of porous materials under microgravity conditions is introduced. On the basis of this, the characteristics and applicable scope of each research method are summarized.
