Abstract
Other Abstract	提出制冷剂气体水合物在纳米流体中快速生成的设想，通过HFC134a气体水合物在纳米铜流体（由0．04％的十二烷基苯磺酸钠（SDBS）水溶液和名义直径为25nm的纳米铜粒子组成）中的生成实验验证了此设想．实验结果表明，与去离子水中HFC134a气体水合物的生成过程相比，纳米铜流体中SDBS是造成HFC134a气体水合物诱导时问明显缩短的主要原因，而纳米铜粒子对诱导时间的影响不大；纳米铜流体中SDBS的乳化作用和纳米铜粒子大比表面积大大促进了HFC134a在水中的溶解；纳米铜粒子的加入明显加强了HFC134a气体水合物生成过程中的传热传质，随着纳米铜粒子数的增加，HFC134a气体水合物生成过程明显缩短． An idea was presumed that the refrigerant gas hydrate could be formed rapidly in nanofluids, so that subsequent experiments were carried on the HFC134a gas hydrate formation process in the nanofluid comprised of 0. 04% sodium dodecylbenzenesulfonate-6solution（SDBS） and nano-copper particles of 25 nm in nominal diameter. The results indicated that, compared with the formation process of HFC134a hydrate in deionized water, the addition of 0.04 % SDBS resulted in much more reduction of induction time of HFC134a gas hydrate than the addition nano-copper did in the nanofluids. The emulation of SDBS and great specific surface of nano-copper particles greatly improved the solubility of HFC134a in water, and the formation process of HFC134a gas hydrate decreased with the mass fraction of nano-copper in nanofluid due to that the addition of nano-copper enhanced the heat and mass transfer of formation of HFC134a gas hydrate.
