摘要：

A plane-radial rotating detonation engine was tested to identify the effects of ignition position on the initiation process of rotating detonation wave, and the RDW establishment processes and operating characteristics under different ignition positions and mass flow rates were investigated. The results show that the RDW's initiation process undergoes three phases: igniter discharge, deflagration to detonation transition and stable rotating detonation. When the ignition position is near the injection surface, the disordered deflagration mode is shortened, and RDW's initiation time decreases with better uniformity. When the ignition position is at the combustor exit, the RDW's initiation time increases obviously under the condition of low mass flow rate. A small increase of mass flow rate effectively shortens the RDW's initiation time, while a significant increase of mass flow rate greatly increases the number of waves in the RDW's initiation process. Under the critical condition of mode transition, changing the ignition position may affect the RDW's initiation mode. When the ignition position is near the center of combustor, it is easy to obtain multi-wave rotating detonation, but changing the ignition position has little effect on the RDE operating mode and detonation-wave parameters in the stable operating process. © 2021, Editorial Department of Journal of Propulsion Technology.
