纳米铝粉及纳米铝粉/煤油凝胶体系能量性能研究

Study on energy performances for nano-aluminum powder and nano-aluminum/kerosene gel system

测定了各单组分及纳米铝粉/煤油凝胶体系的燃烧热,表征了纳米铝粉及纳米铝粉/煤油凝胶体系的能量性能。实验结果表明,随着纳米铝粉含量的增加,纳米铝粉/煤油凝胶体系的质量恒容燃烧热呈降低趋势,这是由于煤油的燃烧热值较高,铝粉的燃烧热值较低所致;而各纳米铝粉/煤油凝胶体系的密度随纳米铝粉含量的增加呈升高趋势,体系的体积燃烧热也随纳米铝粉含量增加而升高。

Combustion heat of every ingredient and nano-aluminum/kerosene gel system was measured, and energy performances of nano-aluminum powder and nano-aluminum/kerosene gel system were characterized. The results show that the mass constant volume combustion heat of the nano-aluminum/kerosene gel system decreases with the increase of nano-aluminum powder content in the gel system. The reason is that combustion heat of nano-aluminum powder is lower than that of kerosene. But density and volumetric combustion heat of the systems increase with increment of nano-aluminum powder content.
