Abstract:In order to explore the propagation characteristics of complex wave and flame in the working process of internal combustion wave rotor, ethylene was used as fuel to carry out experimental research on internal combustion were rotor multi cycle working process. Based on the signal of ion probe, the signal of the pressure sensor and the high-speed photography, the complex wave and flame propagation characteristics in wave rotor channel were analyzed, at the same time, different spoiler structures in the rotor channel were changed to explore the influence of complex wave and flame propagation characteristics. The results show that there is a dynamic process of wave and flame in the wave rotor channel and the distance between the flame and the wave peak is getting smaller and smaller. The flame velocity and pressure wave intensity increased significantly after adding spoiler. When the blockage ratio is 38.91%, the peak pressure at PT2 can reach 1.56MPa. When the blockage ratio is 31.13%, the average velocity of flame propagation can reach 36.95m/s. © 2019, Editorial Department of Journal of Propulsion Technology. All right reserved.
