Feasibility of Large Free-standing Liquid Films in Space | | Rui Zheng

30 Jun 2006 | | Subject: | Soft Condensed Matter | | Abstract: | We consider the feasibility of large-scale free-standing thin liquid film experiment in the space environment as a new realization to study two-dimensional hydrodynamics. We identify material and environmental criteria necessary to avoid freezing, evaporation, chemical degradation, and spontaneous collapse of the film. These criteria pose no obstacles to achieving films of kilometer scale and lifetime of many months, with attainable Reynolds number up to 10^7. However, impacts from meteoroids pose a serious threat to the film, and require substantial shielding or unproven self-healing properties in the film. Current theoretical and experimental studies of two-dimensional turbulence are briefly reviewed. We also describe a specific candidate liquid for the film. | | Source: | arXiv, cond-mat/0606792 | | Other source: | [GID 634964] pmid17279919 | | Services: | Forum | Review | PDF | Favorites | |
