Experimental study of hysteresis and catastrophe in a cavity-based scramjet combustor

Xu Zhang et al.

Summary: Hysteresis and catastrophes were observed in a cavity-based scramjet combustor, breaking traditional knowledge about their relationship with ramjet/scramjet mode transitions. The first hysteresis and catastrophes were attributed to flame stabilization mode transitions, while the second were linked to flame/shock interaction mode transitions.

Numerical investigation of the scale effects of the flame flashback phenomenon in scramjet combustors

Guoyan Zhao et al.

Summary: The study highlights the scale effects of flame flashbacks inside an ethylene-fueled scramjet combustor, showing that larger scale engines have the potential to yield more intense combustion and enhance boundary-layer separation. Differences in boundary-layer profiles may result in accelerated flame propagation speed.

Flame stabilization and local combustion modes in a cavity-based scramjet using different fuel injection schemes

Donggang Cao et al.

Summary: This study investigates the impact of fuel distribution on flame stabilization and local combustion modes in a cavity-based scramjet through numerical simulations. Different injection schemes lead to distinct flame stabilization locations and combustion modes, shedding light on the relationship between fuel injection strategies and combustion performance.

Flame stabilization enhancement by microjet-based virtual shock wave generators in a supersonic combustor

Bin An et al.

Summary: Two flow control methods, microjet array (MJA) and shock wave generator (SWG), were used to enhance chemical reaction in a supersonic combustor. Both methods successfully enlarged the recirculation flow at the strut base and significantly enhanced the combustion, achieving self-sustaining hydrogen/kerosene flames. The study found that MJAs have the potential to replace SWGs in enhancing flame stabilization.

Pilot hydrogen enhanced combustion in an ethylene-fueled scramjet combustor at Mach 4

Ye Tian et al.

Summary: This study investigates the combustion process in an ethylene-fueled scramjet combustor through numerical simulation and experiments, dividing the process into six parts. The combustion process involves nonreacting flow, hydrogen injection leading to shock waves, hydrogen combustion, hydrogen and ethylene combustion, ethylene combustion alone, and flame extinguishing.

Effect of pilot hydrogen on the formation of dynamic flame in an ethylene-fueled scramjet with a cavity

Wen Shi et al.

Summary: The study found that using pilot hydrogen can effectively suppress oscillations in internal flow and improve the stability of ethylene flame in a scramjet. The stability of the pure ethylene flame is poor without pilot hydrogen. Injection of pilot hydrogen ahead of the cavity is crucial for stabilizing the ethylene flame.
