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

Combinations of small quantities of fuel and imposed oscillations are shown to ameliorate
combustion oscillations in ducted flows of premixed methane and air with equivalence ratios …

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 …

Extinction limits are reported for flames stabilized on sudden expansions in plane and round
ducts, with acoustically open and closed upstream ends, with and without downstream …

Concentrations of NOx were measured at the exit of round sudden-expansion combustors
and quantify the effects of oscillations at equivalence ratios between stoichiometry and the …

Velocity and low-frequency combustor pressure oscillations have been measured in a
ramjet dump combustor model. The mean and root mean square (rms) values of the …

The flow of premixed reactants in a duct with flames stabilized on a sudden expansion and
an open downstream end gave rise to combustion oscillations of low frequency due to …

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 …

Combustion oscillations in premixed flames stabilized behind a disk, rearward-facing steps,
and annular rings without and with bypass flow in round ducts have been examined as a …

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