Flame characteristics and a plausible flameholding mechanism in supersonic combustor, with hydrogen injection upstream of cavity flameholder, were investigated the present study. Instantaneous OH radical distribution combustion flowfield was obtained using planar laser-induced fluorescence. According to similarity experimental observations different cavities, typical L/D = 7 chosen, its calculated by large-eddy simulation. The results showed that shear layer plays very important role...
Cavities are widely used as flameholders in supersonic combustors due to their outstanding potential stabilize combustion without excessive total pressure loss. A review of cavity-stabilized for scramjet applications is provided this article. The topics cover the fundamental problems and recent advances regarding cavity-organized high-speed flows, including stabilization modes mechanisms, flame stability analyses correlations, oscillations, other related issues. Remarkable questions such...
The ignition and flame propagation in an axisymmetric supersonic combustor were investigated. laser-induced plasma was employed to ignite the inflow with a speed of Mach 2.5 total temperature 1486 K. A direct-connect model scramjet fully transparent glass built, which enabled circumferential axial cavity-based be visualized by high-speed photography from endoscopic external views, respectively. An initial kernel is produced propagates cavity leading edge along direction. establishment...
The injection and atomization process of a liquid fuel jet is critical for an ignition start scramjet engine. Airwall-mounted crossflow strategy widely used in combustors, avoiding high total pressure loss allowing the to rapidly undergo atomization, mixing, evaporation. In this review, research progress on supersonic was evaluated from aspects mechanism spray characteristics. When injected into crossflow, primary secondary breakups occur successively. surface instability can significantly...
The atomization process of a liquid jet in divergent cavity-based combustor was investigated experimentally using high-speed photography and schlieren techniques under Mach number 2.0 supersonic crossflow. Gas-liquid flow field studied at different angles injection schemes. It is found that complex wave structures exist the combustor. spray can be divided into three distinct zones: surface wave-dominated breakup zone, rapid zone cavity mixing zone. A dimensionless factor defined to describe...
The cavity-assisted scramjet has been proven to be the most promising propulsion system for air-breathing hypersonic vehicles. In this paper, numerical simulations of a Mach 8 axisymmetric combustor are conducted and validated investigate effect cavity. results indicate that combustion state undergoes significant changes as heat release increases. Detailed analysis reveals role cavity in flame stabilization enhancement also with release. Under weak conditions, high-speed environment reduced...
