The frontier in hypersonic flights via an air-breathing scramjet faces a formidable challenge,
because the operational principle is built on thermal compression, which is inherently …

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

We report in situ measurements of non-uniform temperature, H 2 O and CO 2 concentration
distributions in a premixed methane–air laminar flame using tunable diode laser absorption …

The present study is focused on the analysis of non-premixed combustion in high-velocity
(supersonic) flows. The computations make use of a large eddy simulation (LES) model …

ACCURATE measurements of gas dynamic properties such as mass flux, temperature, and
velocity are necessary for the characterization of ground-test facilities and for quantifying …

Large-eddy simulation of a supersonic hydrogen–air non-premixed lifted jet flame is
reported in the configuration studied by Cheng et al.(1994). The emphasis of the study is on …

The paper provides an overview of the use of coherent anti-Stokes Raman scattering
(CARS) and spontaneous Raman scattering for diagnostics of low-temperature …

Planar laser-induced fluorescence of the hydroxyl radical is used to investigate a
cavitybased fuel injection system for scramjet operation at a flight Mach number of 11.5 …

Scramjet engines offer a promising option for powering hypersonic vehicles, although the
unique characteristics of supersonic combustion present numerous challenges. Notably …

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 …
