摘要
采用挂滴法研究了纳米铝粉及表面活性剂（油酸）浓度对正庚烷基纳米流体燃料着火特性的影响,用热电偶测量了管式电阻炉内温度为500℃时液滴及其附近的气相温度随时间的变化.结果表明,随油酸浓度增加,纳米流体燃料的着火温度显著升高;随纳米铝粉浓度增加,纳米流体着火温度明显降低.
The effects of various concentrations of nanoaluminum powder and surfactant（oleic acid） on the ignition characteristics of heptane-based nanofluid fuel as suspend droplets were investigated. Two thermocouples were employed to measure the droplet temperature and the gas temperature near the droplet when the resistance furnace temperature was 500℃. The results showed that the ignition temperature increased significantly with the increase of oleic acid concentration. The ignition temperature decreased significantly with increasing nanoaluminum concentration.
