Abstract

The paper presents an experimental study of the process of methane hydrate formation from stabilized water foam. In all cases, the hydrate formation front started from the region inside the foam. Upon reaching the foam-solution boundary, it initiated the formation of polycrystalline conical conglomerates at this boundary - hydrate needles oriented deep into the solution. A mechanism for their formation and subsequent spontaneous shortening of some of them is proposed.

表面活性剂界面泡沫溶液中甲烷水合物多晶聚集体形成的若干特征

本文对稳定水泡沫生成甲烷水合物的过程进行了实验研究。在所有情况下，水合物的形成前沿都是从泡沫内部的区域开始的。到达泡沫-溶液边界后，在该边界处开始形成多晶圆锥形砾岩——水合物针状结构深入到溶液中。提出了它们的形成和随后的一些自发缩短的机制。

期刊介绍： Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
