摘要

摘要: 纳米流体燃料是将纳米颗粒添加至液体燃料中形成的一种悬浮液，具有高能量密度、点火延迟时间短等优点，具有改善燃料燃烧特性的潜力。为探寻更为有效的纳米流体燃料性能调控方法，本文回顾了近年来国内外纳米流体燃料性能调控的研究进展，主要介绍了纳米流体的稳定性能、流变性能、蒸发性能、点火性能和燃烧性能调控的研究成果，分析了各种物理和化学调节方法及其基本原理。添加表面活性剂和金属包覆改性是改善纳米流体燃料稳定性能和流变性能的主要方法；点火性能和燃烧性能的调控主要基于提高燃料液滴热传导和热辐射吸收能力、促进金属颗粒自身释热等途径，主要包括添加纳米金属颗粒、纳米金属氧化物及新型亚稳态分子间复合物等。纳米流体燃料的下一步研究应重点围绕拓宽纳米流体燃料界限、探索新型表面活性剂、建立纳米流体燃料点火燃烧理论体系等方面展开。

Abstract: Nanofluid fuel is a kind of suspension liquid, which is made by adding nanoparticles into the liquid fuel. It has advantages of high energy density and shorter ignition delay, and thus shows the potential of improving the burning characteristics of the fuels. To further improve the performance of nanofluid fuels and explore more effective performance control methods, the progress of research on nanofluid fuels in recent years at home and abroad is briefly reviewed in this work. Researches on the improvement of the stability performance, rheological performance, evaporation performance, ignition performance and combustion performance of nanofluid fuels are introduced, and the corresponding tailoring methods and mechanisms are analyzed. Adding surfactant and surface coating are effective methods to improve the stability of nanoparticles in the fuel. The methods of regulating ignition and combustion performance are based on improving the heat conduction and absorption capacity of droplets and promoting the heat release of metal particles, which mainly include nano-metal particles, nano-metal oxides, and new metastable intermixed composites. The existing problems in current research are summarized. More importantly, it is pointed out that the future study of nanofluid fuels should focus on broadening the boundary of the fuel, exploring new surfactants, and establishing the theoretical framework of ignition and combustion.
