This study aims to provide a comprehensive overview of rotating detonation engine focusing on the experimental equipment, methodologies and parameters used. The purpose is to identify trends, gaps and opportunities to guide the development of efficient and cost-effective rotating detonation engines (RDE).
The study systematically presents key components and techniques used in RDE experiments, including mass flow controllers, valves, data acquisition systems, high-speed visualization, thrust measurement devices, pressure sensors, predetonation tubes and ignition systems.
RDEs offer significant potential advantages over traditional combustion engines, including pressure gain combustion, improved thermodynamic efficiency and compact design. However, challenges related to detonation wave stability, mixing and run time have limited their practical implementation. Recent advancements in high-speed diagnostics, manufacturing and control systems have enabled accelerated RDE research.
This study improves the value to the field of RDE research by consolidating and analyzing the diverse experimental techniques and equipment used worldwide. By providing a comprehensive and systematic overview of the key components, methodologies and parameters, this work identifies the recommend method, common challenges and potential solutions. The insights gained from this review can help streamline future research efforts and accelerate the development of practical, efficient and cost-effective RDE.
