Combustion oscillations in industrial combustion chambers
Symposium (International) on Combustion, 1969Combustion roar is a “white” noise radiated from small regions in the flame which suddenly burn. Single frequency oscillations of the simple acoustic type in the combustion chamber (“screaming”) have a frequency 500 cps upwards; Helmholtz resonator oscillations have a frequency of the order of 10 times lower and occur fairly frequently in oil- and gas ...

Stability of the combustion process in elastic combustion chambers
Journal of Applied Mechanics and Technical Physics, 1968High-frequency instability phenomena in rigid combustion chambers have been studied theoretically in [1–3]. This phenomenon is attributed to the interaction between the combustion processes and combustion-product fluctuations in the chamber. One of the possible mechanisms of formation of high-frequency instability is examined in [3], where the ...

Gasoline Engine Combustion—Turbulence and the Combustion Chamber
SAE Technical Paper Series, 1981<div class="htmlview paragraph">A research programme has been carried out to investigate the effects of operating gasoline engines with different combustion systems. The results showed that at high compression ratios (13:1) compact combustion chambers allowed an increase in compression ratio of between 1 and 2½ numbers for a given fuel quality ...

Bipropellant combustion in a liquid rocket combustion chamber
Journal of Propulsion and Power, 1992A comprehensive computer simulation code is developed for the combustion-flow analysis of a bipropellant liquid rocket engine combustor. A bipropellant group combustion model is built in the computer code to facilitate the determination of various combustion modes, including the combustion of oxidizer droplets, fuel droplets and gas mixture.
