Continuously rotating detonation waves of thousands of Hz, indicating the merit of continuously rotating detonation waves that ignite only once to keep working, are experimentally gotten in the combustion chamber designed by Peking University. The steady continuously rotating detonation waves have jarless peak pressures and cycles microcosmicly, showing that during this stage, flux, pressure and temperature of working medium are steady. However, transition regions do exist between two groups of steady continuously rotating detonation waves. Related data of transition regions are fitted to find out the basic rule. The paper also figures out the velocity of ideal detonation waves by C-J theory, and obtains the cycle and number of continuously rotating detonation waves with experimental data. |
