Abstract Nano additives in fluid has been of great interest for researchers in recent times due to the improvement in heat carrying capacity. The current study focuses on the effect of temperature on the ignition behaviour of nano additive with refined kerosene. The investigation is carried out for volume fractions of 0.01%, 0.05% and 0.1% of alumina-refined kerosene and aluminium-refined kerosene respectively. Two different experimental methods are used to investigate the ignition behavior of seeded refined kerosene. First method: The ignition probability was measured experimentally using hot plate. The temperature range studied for ignition probability is from 200 °C to 480 °C. Second method: Tests were carried out in shock tube to determine ignition delay of the seeded refined kerosene. The study is carried out for the temperature range of 950–1450 K in a shock tube. The driven section of the shock tube is maintained at an oxygen-rich condition. The pressure range is limited to 4–10 at m. The experimental investigations confirms, irrespective of alumina or aluminum nanoadditives the ignition probability increased with the increase in temperature. The ignition probability also increased with an increase in volume fraction of seeded refined kerosene. However the ignition delay did not have much significant effect on the low volume fraction of 0.01 % and 0.05 %. With the increase in volume fraction and temperature, the effect on ignition delay is prominent.

温度对种子精制煤油着火行为影响的实验研究

摘要 近年来，流体中的纳米添加剂由于其传热能力的提高而引起了研究人员的极大兴趣。目前的研究重点是温度对纳米添加剂与精制煤油的着火行为的影响。分别对体积分数为0.01%、0.05%和0.1%的氧化铝精制煤油和铝精制煤油进行了调查。使用两种不同的实验方法来研究种子精制煤油的点火行为。第一种方法：使用热板通过实验测量点燃概率。研究点火概率的温度范围为 200 °C 至 480 °C。方法二：在激波管中进行测试，以确定种子精制煤油的点火延迟。该研究是在激波管中 950-1450 K 的温度范围内进行的。激波管的驱动部分保持在富氧状态。压力范围限制在 4–10 at m。实验研究证实，无论是氧化铝还是铝纳米添加剂，点火概率都随着温度的升高而增加。着火概率也随着种子精制煤油体积分数的增加而增加。然而，点火延迟对 0.01% 和 0.05% 的低体积分数没有太大影响。随着体积分数和温度的增加，对点火延迟的影响显着。实验研究证实，无论是氧化铝还是铝纳米添加剂，点火概率都随着温度的升高而增加。着火概率也随着种子精制煤油体积分数的增加而增加。然而，点火延迟对 0.01% 和 0.05% 的低体积分数没有太大影响。随着体积分数和温度的增加，对点火延迟的影响显着。实验研究证实，无论是氧化铝还是铝纳米添加剂，点火概率都随着温度的升高而增加。着火概率也随着种子精制煤油体积分数的增加而增加。然而，点火延迟对 0.01% 和 0.05% 的低体积分数没有太大影响。随着体积分数和温度的增加，对点火延迟的影响显着。
