Combustion Oscillation in Oil Mist Firing
This paper deals with the unstable combustion of liquid fuel in a combustor. Owing to the increase of air-fuel ratio in the range larger than stoichiometric one, combustion becomes unstable, the noise increases and also the pressure and the temperature in the combustor oscillate at a frequency of 20 to 50 cps. Moreover, blow-off phenomenon results from

Coupled vortex shedding and acoustic resonances in a duct [PDF]
Undesirable sound generation in the combustion chambers of solid propellant rocket motors previously has been attributed to vortex shedding from obstructions that are uncovered as the propellant burns back. An experimental investigation of the phenomenon

Thermoacoustic Analysis of Combustion-Driven Oscillation.
Thermoacoustic analysis of heat-driven oscillation with steady flow is performed. Comparing the results with Katto's experiment on the Rijke tube and our experiment on combustion-driven oscillation with multispud gas burner which is previously reported, the following results are obtained : (1) In acoustic-type combustion-driven oscillation, one of the ...
