AbstractIn this paper we numerically investigate the effects of various geometrical parameters of a backward wave oscillator (BWO), filled with a magnetized plasma of uniform density and driven by a mild relativistic solid electron beam, on the instability growth rate (Γ) of a free electron laser (FEL). The FEL instability is numerically calculated and the result is compared with the instability growth rate of an annular electron beam for the same set of parameters. The instability growth for a solid electron beam scales inversely to the seventh power of relativistic gamma factor γ0 and directly proportional to the corrugation amplitude.

Thermoacoustic Oscillations

An approach for modeling combustion instabilities in annular combustors is presented. The main feature that distinguishes the method from other existing approaches is the coupled consideration of acoustics of multiple burners in an annular arrangement. The developed method allows modeling of annular combustors with an arbitrary number of different burners. The influence of azimuthal nonuniformities due to different burner characteristics on the combustor pulsations in a gas turbine combustor is investigated. It is shown that the instability growth rate is strongly influenced by the burner arrangement.
