Cavities are widely used as flameholders in supersonic combustors due to their outstanding
potential to stabilize combustion without excessive total pressure loss. A review of cavity …

TWO characteristics of flames that are stabilized in a directly fueled rectangular cavity are
reported in this Note. They are 1) the flame location within the cavity at different fueling rates …

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 …

Recesses in the walls of supersonic combustion chambers–cavities–have emerged as a
preferred flameholding device since they are non-intrusive, hence resulting in reduced drag …

Quantitative fuel distribution measurements employed spontaneous Raman scattering
technique were made around a cavity in a Mach 2 non-reacting flow. Gaseous fuel was …

The characteristics of cavity-based supersonic flow and combustion in a scramjet combustor
are investigated both experimentally and numerically. Cavities with depth D= 8 mm, length …

A key component for the opembility of a scramjet system is the flame holder. This study
investigated the flame holding properties of recessed cavities in supersonic flow using …

Experiments were performed to examine the stability of hydrocarbon-fueled flames in cavity
flameholders in supersonic airflows. Methane and ethylene were burned in two different …

This paper presents experimental data examining the flameholding performance of a
scramjet cavity with an inclined front wall. Mach 8 flight-equivalent flows were delivered to …

This paper investigates the impact of fuel distribution on flame stabilization and local
combustion modes in a cavity-based scramjet. Two injection schemes with a global …
