| 摘 要： | 改进烟迹技术之后，在初始为常温常压的条件下，进行了碳氢混合燃料（C5~C6）的气云爆轰胞格结构实验研究，得到了清晰的胞格烟迹记录，同时讨论了燃料气云的当量比和起爆能对胞格结构的影响。实验表明：C5~C6混合燃料的爆轰波胞格宽度和胞格长度均随当量比的增加而线性增大；随着起爆能的不断增大，混合燃料的胞格宽度和胞格长度均是先增大后减小，且当起爆能足够高时，在胞格结构内可观察到精细结构的存在。

| Abstract: | The detonation cellular structures caused by C_5~C_6 cloud fuel mixtures are studied under the initial atmospheric pressure and room temperature by improved soot foil technique.Sharp cellular patterns are obtained.Meanwhile,the effect of equivalence ratio and initiation energy on the detonation cell size are also discussed respectively.The experimental results show that the detonation cell size of C_5~C_6 increases almost linearly with the increase of the equivalence ratio,but the detonation cell size increases first then decreases with the increase of the initiation energy.Moreover,when the initiation energy gets high enough,the fine structures in cellular structures are observed. |
