Measurements of pressure fluctuations in sudden-step expansion flows of round cross-
section are examined to determine the effect of matching the fluid-dynamic frequency …

Experiments have been performed to quantify the isothermal and combusting flows
downstream of a plane sudden-expansion. The detailed measurements correspond to an …

Measurements of mean values of velocity, temperature and concentrations of carbon
monoxide, carbon dioxide, unburned hydrocarbon, and oxygen have been obtained in the …

The oscillations that occur in ducted plane and round sudden-expansions with combustion
of premixed air and methane have been examined for flow conditions which gave rise to …

Low-frequency combustion instabilities are studied in a model ramjet combustor facility. The
facility is two-dimensional, and is comprised of a long inlet duct, a dump combustor cavity …

Low frequency pressure oscillations in a research ramjet combustor have been studied
using an integral technique. The analysis deals with plane one-dimensional oscillations with …

Velocity and noise characteristics have been measured in the flow in a model combustor,
which allows the simulation of combustion oscillations similar to those observed in …

Previous researchers have demonstrated that strong pulsations of the fuel flow rate can
significantly reduce the flame length and luminosity of laminar/transitional non-premixed jet …

The role of flow coherent structures as drivers of combustion instabilities in a dump
combustor was studied. Results of nonreacting tests in air and water flows as well as …

THE role of the shear layer's large-scale turbulent struc-tures in mixing processes and jet
noise generation has been studied over the past 10 years. 1'4 Recent attention has been …
