Journal ArticleDOI
Cavity Flame-Holders for Ignition and Flame Stabilization in Scramjets: An Overview
Adela Ben-Yakar,Ronald K. Hanson +1 more
TL;DR: In this article, the authors describe ongoing research efforts in the scramjet community on cavity e ame holders, a concept for holding and stabilization in supersonic combustors, and discuss open questions impacting the effectiveness of the cavities as a holding device.
Journal ArticleDOI
Fundamental Studies of Cavity-Based Flameholder Concepts for Supersonic Combustors
TL;DR: In this paper, the authors investigate the effect of the aft ramp angle on the character of the shear layer that spans the cavity in a nonreacting supersonic ship.
Journal ArticleDOI
A review of cavity-based trapped vortex, ultra-compact, high-g, inter-turbine combustors
TL;DR: Trapped vortex combustion (TVC) as mentioned in this paper is a promising combustion concept that has been extensively studied in the application areas of aerospace propulsion, power generation and waste incineration, where a large rotating vortex can be formed in the cavity and is thus named a locked vortex.
Journal ArticleDOI
Characteristics of a Trapped-Vortex Combustor
TL;DR: In this article, the characteristics of a trapped-vortex (TV) combustor are described and the instantaneous shape of the recirculation zone of the trapped vortex is measured using a two-color PIV technique.
Supersonic Combustion Experiments with a Cavity-Based Fuel Injector (Postprint)
Tarun Mathur,Mark R. Gruber,Kevin Jackson,Jeff Donbar,Wayne Donaldson,Thomas A. Jackson,Fred Billig +6 more
TL;DR: In this paper, a direct-connect supersonic combustor was used to simulate flight conditions between Mach 4 and 6 at a dynamic pressure of 47.9 kPa and achieved sustained combustion at equivalence ratios between 0.25 and 0.75 using only a spark plug and no other external ignition aids.

Suppression of flow-induced pressure oscillations in cavities
R. L. Sarno,Milton Franke +1 more
TL;DR: In this article, the effects of manipulating the shear layer over the cavity leading edge are examined for suppressing flow-induced pressure oscillations in a shallow cavity resulting from tangential flows over the cavities.

An investigation of supersonic oscillatory cavity flows driven by thick shear layers
Xin Zhang,J.A. Edwards +1 more
TL;DR: In this article, the effects of variations in Mach number and length to depth ratio of a two-dimensional rectangular cavities driven by thick shear layers are investigated experimentally at two supersonic Mach numbers (Me = 1.5 and 2.5).
