Application of Active Combustion Instability Control to a Heavy Duty Gas Turbine
Joerg R. Seume,Nicolas Vortmeyer,W. Krause,J. Hermann,C.-C. Hantschk,P. Zangl,Stephan Gleis,D. Vortmeyer,A. Orthmann +8 more
TL;DR: In this paper, a feedback system was developed which counteracts combustion instabilities by modulation of the fuel flow rate with rapid valves (active instability control, AIC), which achieved a reduction of combustion-induced pressure amplitudes by 86 percent.

Numerical simulation of self-excited thermoacoustic instabilities in a rijke tube
C.-C. Hantschk,D. Vortmeyer +1 more
TL;DR: In this paper, two different kinds of Rijke tubes are modelled by using a control volume based finite difference method to solve iteratively the unsteady conservation equations for mass, momentum and energy.

Acoustical oscillation in a combustion system with a flat flame
H. Schimmer,D. Vortmeyer +1 more
TL;DR: In this paper, a flat flame is stabilized by a copper matrix burner with about 700 deep ports and burns in a resonator tube (diameter 30 nm) of the same area.

Self-excited oscillations in combustion chambers with premixed flames and several frequencies
F. Joos,D. Vortmeyer +1 more
TL;DR: In this article, the authors present experimental results of self-excited oscillations in combustion chambers, using a simple laboratory burner with flames of small extension, for situations when more than one frequency is excited and, owing to the unsteady sound field, phase shifts vary continually between sound pressure and sound particle velocity.
