A reverse-flow combustor has a larger liner surface area due to airflow turning, which complicates flow and cooling control, particularly heat transfer efficiency. Effective management is essential for maintaining uniform temperature distribution preventing thermal gradients. This study explores the impact of axial position diameter primary holes on performance dynamics. Results indicate that as move toward dome, recirculation vortex size decreases, leading insufficient fuel mixing,...

Abstract To enable stable performance in a rotating detonation combustor (RDC) operating with aviation fuel and air mixtures, this study develops novel RDC configuration for hydrocarbon/oxidizer systems. The experimental investigation focuses on characterizing both non-reactive flow patterns high-energy combustion phenomena under diverse supply parameters, employing premixed injection strategies initial validation. Under gas conditions, wave (RDW) mode was successfully established. pressure...

Centrally staged combustion technique is often used in the military high-temperature-rise combustor. The pilot-stage structure affects flow characteristics centrally combustor, which further performance of ignition, combustion, and emission aero-engines. In order to increase capacity swirler, swirler with a non-rotating channel was designed. this work, influences on combustor are investigated. fields combustors different swirl numbers (0.44, 0.60, 0.71) analyzed by large eddy simulation...

Efficient initiation of oblique detonation waves (ODWs) is crucial for optimizing the performance wave engines. A novel approach proposed enhancing ODW through expansion in this research. Validation wave-reinforced method conducted via numerical simulations employing multi-species reactive Euler equations and a pressure-dependent reaction mechanism. Results demonstrate significant reduction length ODWs with addition an ahead wedge, contrasting absence on wedge lacking wave. theoretical...
