Recesses in the walls of supersonic combustion chambers–cavities–have emerged as a
preferred flameholding device since they are non-intrusive, hence resulting in reduced drag …

A nanosecond pulsed plasma discharge located within a wall cavity is used to ignite jet
flames (hydrogen and ethylene) in supersonic crossflows. The nonequilibrium plasma is …

In this study, a hybrid large-eddy/Reynolds-averaged Navier–Stokes (LES/RANS) method is
used to simulate ethylene combustion inside a cavity flameholder. The cavity flameholder …

The self-ignition characteristics of a solid fuel under supersonic flow have been investigated
theoretically and numerically. Time-dependent two-dimensional axisymmetric compressible …

Atmospheric pressure flow reactor experiments were performed to measure the ignition
delay times of JP7, JP8, and S8 fuels between 900 K and 1200 K. The equivalence ratio of …

of scramjet engines with accurate combustion modeling is generally prohibitively expensive …

The development of a reactive flow solver suitable for large-scale simulations of high-speed
engine component flow fields is described in this paper. The intent is to mature an existing …

The turbulent flame inside a gas turbine engine is susceptible to local extinction leading to
global extinguishment or blowout at fuel lean conditions. Flame blowout is traditionally …

Since hydrocarbon fuels are the likely fuel of choice for scramjet propulsion in the near term,
the capability to accurately predict dual-mode cavity flameholder combustors must be …

A turbulence model that allows for the calculation of the variable turbulent Prandtl (Pr t) and
Schmidt (Sc t) numbers as part of the solution is presented. The model also accounts for the …
