A review of fundamental research in combustion stabilization for hypersonic airbreathing
propulsion is presented. Combustion in high-speed airbreathing propulsion systems …

The dual-mode scramjet combustor is a promising candidate for the combined cycle engine
of the hypersonic airplane, and the flame propagation and stabilization process in the dual …

In order to strengthen the internal flow and heat transfer and increase the stability of the
flame, various methods to improve combustion efficiency were proposed. In terms of spatial …

Optical diagnosis-based combustion experiments were conducted to investigate the
characteristics of cavity assisted hydrogen jet combustion in a supersonic flow with a total …

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 …

The major issue in improving the efficiency of the scramjet engine is ensuring adequate
hydrogen fuel distribution within the supersonic chamber. Recently cavity floor injection …

We present high-fidelity reacting simulations of a supersonic cavity flame-holder
configuration. The focus of this work is on flame stabilization brought about by varying the …

The spark ignition process in the scramjet combustor fueled by hydrogen equipped with
multi-cavities at Mach 4 flight condition was observed by high speed photography and …

Behaviors of premixed CH 4/air flame in mesoscale channels with and without cavities were
experimentally investigated. No stable symmetric flame was observed in the channel without …

Flame characteristics and a plausible flameholding mechanism in a supersonic combustor,
with hydrogen injection upstream of a cavity flameholder, were investigated in the present …
