Combined-cycle engine is a potential propulsion system for hypersonic aircraft. To ensure
long-term, normal operation of combined-cycle engine under the harsh environment of high …

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 …

Hybrid large-eddy/Reynolds-averaged Navier–Stokes simulations of turbulence/chemistry
interactions occurring within a ramp-injected, hydrogen-fueled scramjet combustor are …

Time-resolved CH* chemiluminescence imaging was performed at 50 kHz in order to study
flame motion and stabilization in the axial flow direction in a dual-mode scramjet at the …

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

Here, we report on large-eddy simulation (LES) of supersonic flow, mixing, self-ignition, and
combustion in a model scramjet combustor. The combustor has been experimentally …

The combustion process is complex and harsh, and the supersonic combustion flow field is
also characterized by short duration and supersonic speed, which makes the real-time …

Ignition in a supersonic hydrogen–air mixing layer interacting with an oblique shock wave is
investigated analytically under conditions such that the postshock flow is supersonic and the …

Particle image velocimetry was performed in the spanwise centerplane of a scramjet cavity
flameholder under premixed hydrocarbon-fueled dual-mode conditions, providing the first …

Schlieren imaging is particularly suited to measuring density gradients in compressible
flowfields and can be used to capture shock waves and expansion fans, as well as the …
