Abstract

The impact of nitromethane on the explosion characteristics of diethyl ether -aluminium powder mixed fuel in the presence of different ambient factors is studied in a 20 L sphere-shaped explosion vessel. The explosion pressure of the fuel is obtained by a series of experiments, and the mechanism of nitromethane during these experiments is deduced by analysing the maximum rate of pressure increase and the gas products. The results showed that a synergistic effect existed between nitromethane and diethyl ether at high mass concentrations. The self-decomposition reaction of nitromethane enables high mass concentration fuels to react more fully, maintaining a higher explosion pressure under a low-pressure or high-relative humidity environment.
