氨氢燃料激光点火特性实验和模型研究
Experimental and Model Study on Laser Ignition Characteristics of Ammonia-Hydrogen Fuel
基于定容燃烧平台，对不同掺氢比(0~20%)、不同当量比(0.6~1.4)及不同初始压力(0.1~0.4MPa)的氨氢混合气进行了激光点火实验，对不同条件下的火焰发展状态、点火成功率及最小点火能量的变化进行了分析，同时提出了能直接预测不同工况混合气的最小点火能量优化模型。结果表明：提高掺氢比和初始压力均能明显提高火焰稳定性及降低最小点火能量，在掺氢比为10%或初始压力为0.2MPa时，降低效果最明显，但继续提高掺氢比或压力，降低幅度会逐渐减小；当…查看全部>>
Based on the constant volume combustion chamber, laser ignition experiments were carried out on ammonia-hydrogen mixture with different hydrogen mixing ratio (0~20%), different equivalence ratio (0.6~1.4) and different initial pressure (0.1~0.4MPa). The flame development morphology, probability of ignition and minimum ignition energy changes under different conditions were analyzed. At the same time, a minimum ignition energy optimization model is proposed w…查看全部>>
