Experiments are performed to investigate the near blowoff characteristics of cavity-stabilized
flames in an ethylene-fueled scramjet combustor. Heated air enters the combustor with …

The species concentrations of flame chemiluminescence play important role in combustion
diagnostics, such as CH* and C2* of hydrocarbon flame, which can provide specific …

Particle image velocimetry was performed in the spanwise centerplane of a scramjet cavity
flameholder under premixed hydrocarbon-fueled dual-mode conditions, providing the first …

Lean blow-out (LBO) and thermoacoustic instability (TAI) are common undesirable
occurrences in modern lean-burn turbulent combustion systems, such as fossil-fuel furnaces …

Lean blowoff characteristics of an ethylene-fueled model scramjet combustor with cavity
flameholder are investigated under the inflow conditions of Ma= 2.52 and T 0= 1600 K. It is …

The ignition and blowout characteristics have a significant impact on the performance and
operating limit of the scramjet. In this study, direct-connected ground tests of a typical …

In this work, a numerical approach is used to investigate the effects of level and type of
stratification on turbulent methane-air stratified combustion. Two different scenarios are …
