Combustion environments in propulsion systems involve the interaction of a variety of
physics. In devices such as augmentors, ramjets and scramjets, such environments include …

This paper investigated the combustion instability of spanwise positions in a hydrogen
fueled scramjet combustor with a cavity flame holder. High-speed OH-PLIF technique was …

The incorporation of cavities within supersonic combustion chambers is an effective means
of slowing down the flow for fuel injection and consequent stable combustion …

A new pulsed-arc-heated hypersonic wind tunnel facility, designated as ACT-1 (Arc-heated
Combustion Test-rig 1), has been developed and built at the University of Notre Dame in …

Numerical simulations of the turbulent reactive flow within a model scramjet combustor
configuration, experimentally mapped at the University of Virginia's Scramjet Combustion …

Hypersonic airbreathing engines rely on scramjet combustion processes, which involve high-
speed, compressible, and highly turbulent reacting flows. The combustion environment and …

Abstract The Supersonic Combustion Ramjet (SCRAMJET) engine has been recognized as
one of the most promising air breathing propulsion system for the supersonic/hypersonic …

In this paper, the authors describe dual-pump coherent anti-Stokes Raman spectroscopy
(CARS) measurements of mixing and combustion in a direct-connect scramjet combustor …

Closed-loop fueling control of a dual-mode scramjet was successfully demonstrated using
optical emission spectroscopy as the sole sensor for controller feedback. The optical …

The flame front of a premixed ethylene–air turbulent flame in a high-speed flowfield was
imaged using hydroxyl radical (OH) planar laser-induced fluorescence (PLIF). An electrically …
