Abstract:
For the purpose of enhancing the stability of nanofluid fuels, scholars are seeking a more effective approach of metal particles modification. Development process of nanofluidic fuels as well as theoretical researches on its stability are briefly reviewed in the article, with focusing on the technical approaches to improve the stability of nanofluid fuels and the modification methods of metal particles. The stability mechanism of nanofuels is firstly introduced from two aspects: influencing factors and DLVO theory. The stability evaluation methods applied to nanofluid fuels are briefly described with that. After that, the preparation methods of nanofluid fuels are reported. In addition, it is pointed that using surfactants and surface modification of metal particles are principal means for improving the stability of nanofluid fuels and that surface modification of metal particles is an effective solution for both stability and combustion of nanofuels. Finally, after analyzing the related researches on the surface modification of boron and aluminum particles, the approaches and results of metal particles modification are summarized, and the future research trends are prospected.
