Experimental Study on the Propagation Characteristics of Rotating Detonation Wave with Rich Combustion Gas in Solid Ram Engine
In order to study the rotational detonation characteristics of rich combustion gas in solid ramjet engines, this paper replaces solid rich combustion gas with CH4/CO/H2 mixture as fuel and uses ambient temperature air as oxidant to investigate the propagation characteristics of rotational detonation...

| description | In order to study the rotational detonation characteristics of rich combustion gas in solid ramjet engines, this paper replaces solid rich combustion gas with CH4/CO/H2 mixture as fuel and uses ambient temperature air as oxidant to investigate the propagation characteristics of rotational detonation waves in the mixture. The experimental research results show that a mixture mass ratio of 1∶4.4∶0.67, a mass flow rate of 54.5 g/s, and an air mass flow rate ranging from 370.9 g/s to 782.3 g/s can detonate and form stable rotating detonation waves. With the increase of air flow, the propagation mode of rotating detonation undergoes a process of single wave, double wave collision to four wave collision. The propagation speed of the detonation wave showed a change of first increasing and then decreasing. When the air mass flow rate is 484.9 g/s and the equivalence ratio is 0.95, the maximum detonation velocity is 1 167.8 m/s. |
