Abstract
In order to investigate the propagation mode of rotating detonation wave in rotating detonation engine (RDE) with different annular gap width, the experiment was conducted on non-premixed RDE. During the experiment, high-frequency pressure transducers, ion probes and high-speed photography were used simultaneously. Under the condition of the same inlet mass flow rate, the annular gap width of air inlet and detonation chamber were changed. As a result, the propagation mode including the single wave, double wave, four wave collision and mixed mode were obtained. By analyzing the experimental results, it was found that when the detonation chamber width was 6 mm, the detonation wave was changed from four wave collision to double wave, and finally to the single wave as the air inlet width was increased. When the detonation chamber width were 10 and 15 mm, the air inlet width had little influence on detonation wave propagation mode. In addition, under the four wave collision mode, both of the pressure peak and ion signal peak were lower than that of the single wave and double wave modes.关键词
