Energy Release Mechanism of AP-coated Micro/Nano-structured Aluminum Powder
摘要
Abstract
To enhance the reactivity and energy release efficiency of aluminum powder fuel,ammonium perchlorate(AP)-coat-ed micro/nano composite aluminum powder was prepared via a liquid-phase deposition-spray drying method.Scanning electron microscopy(SEM),calorific value measurements,Hartmann tube flame propagation tests,and high-speed infrared imaging were employed to systematically investigate the effects of the AP-coated micro/nano structure on combustion performance.The results indicate that,in the uncoated system,the sample with 18%nano-aluminum exhibited the most uniform particle surface distribution,achieving a calorific value of 31.3 MJ·kg-1.In the AP-coated system,high reactivity was maintained even at elevat-ed nano-aluminum contents,with the 24%nano-aluminum sample exhibiting a calorific value of 27.5 MJ·kg-1.AP coating signif-icantly increased the flame propagation velocity and advanced the peak occurrence time;for the 18%nano-aluminum sample,the maximum flame propagation velocity increased from 62.81 to 67.50 m·s-1.Infrared imaging results indicate that AP coating reduces the peak flame temperature and shifts the high-temperature zone from edge-enhanced to centrally concentrated.关键词
