本文对SiC/H_2O和石墨/H_2O纳米流体流动沸腾传热特性进行了实验研究。与基础流体相比，纳米流体的流动沸腾换热性能有增强和减弱的趋势，0.1vol与去离子水相比，SiC/H2O纳米流体的溶解度从-24.7%变化到30.6%。相反，对于0.1 vol.%，其从-29.4%变为13.3%石墨/水纳米流体。此外，还从机理的角度对这一现象进行了辅助和抵抗。这些辅助作用包括：热物理性能的提高，表面张力和潜热的降低，接触角的减小，表面能的降低。相反，阻力主要是沸腾点数量的减少。
In present work, the heat transfer characteristics of SiC/H2O and Graphite/H2O nanofluids flow boiling are experimentally studied with the consideration of pressure, mass flux and heat flux. Compared with based fluid, both enhancement and deterioration of nanofluids boiling heat transfer are found. The flow boiling heat transfer capacities of 0.1vol.% SiC/H2O nanofluid is changed from -24.7% to 30.6% compared with deionized water. Instead, it is changed from -29.4% to 13.3% for 0.1vol.% Graphite/H2O nanofluid. In addition, a mechanism of this phenomenon from the point of view of the assistance and resistance. The assistance includes the improving of the thermal physical properties, the decreasing of surface tension and latent heat, the decreasing of contact angle, decreasing of the surface energy. Instead, the resistance is mainly the decreasing of the number of boiling site.
