Abstract
In order to investigate the effect of oxygen content on energy release characteristics of liquid-solid mixed fuel air explosive ( FAE ) , the isothermal calorimeter and closed explosion system were developed respectively. The detonation heat of FAE under different oxygen content was tested by the calo-rimetric method,and the quasi-static pressure of FAE under different oxygen condition was measured by using PCB piezoelectric pressure sensors. The FTIR spectrascopy was also used to test and verify the detonation gas product. The results show that the detonation heat value increases with the increase of the oxygen content,and the content of CO and CO2 increase,and the content of HCN increases firstly and then decreases rapidly, and the content of CH4 decreases gradually. In standard condition and oxygen condition,the quasi-static pressure is 0. 255 MPa and 0. 310 MPa respectively. All of these indicate that with the increase of the oxygen content, the oxidbility of FAE enhances gradually, and more enengy is released. The energy release rate of liquid-solid mixed FAE increases significantly.关键词
