碳氢燃料爆轰波胞格结构的实验研究

Experimental Studies on the Cellular Structure of Detonation Waves of Hydrocarbon Fuels

在实验的基础上,对碳氢燃料云雾爆轰波胞格结构的影响因素进行讨论分析认为:初始温度的变化对胞格尺寸的影响较小;胞格尺寸随初始压力的降低而增大;稀释气体使碳氢燃料的爆轰波胞格尺寸增大,在稀释气体达到一定浓度后,胞格尺寸将迅速增大;起爆能的增大可以导致更加复杂的爆轰波次胞格结构出现。

On the basis of the affecting factors on the cellular structure of detonation waves of hydrocarbon fuels spraying in air,it can be concluded that a change in initial temperature shows a little influence on the cell size,while the cell size increases with the decrease of initial pressure. Furthermore,the presence of a certain amount of inert gases,such as nitrogen,can enlarge the cell size. The enhance of initiating energy will lead to a more complex cellular structure.
