In many continuous combustion processes, such as those found in aeroengines or gas
turbines, the flame is stabilized by a swirling flow formed by aerodynamic swirlers. The …

This paper deals with the dynamics of standing and rotating azimuthal thermoacoustic
modes in annular combustion chambers. Simultaneous acoustic measurements have been …

Abstract Direct Numerical Simulations (DNS) are performed to investigate the process of
spontaneous ignition of hydrogen flames at laminar, turbulent, adiabatic and non-adiabatic …

Gas turbine combustors are prone to undesirable combustion dynamics in the form of
thermoacoustic oscillations. Analysis of the stability of thermoacoustic systems in the …

The recent development of the Alstom's sequential combustion system for the GT24 (60Hz)
and GT26 (50Hz) upgrades 2011 is a perfect example of evolutionary design optimizations …

Fur die freundschaftliche, offene und hilfsbereite Atmosphäre möchte ich mich bei allen
wissenschafltichen Mitarbeitern des Fachgebietes bedanken. Besonders die …

The Ultra-High Efficiency Gas Turbine Engine (UHEGT) was introduced in our previous
studies [1]–[3]. In UHEGT, the combustion process is no longer contained in isolation …

Alstoms GT24 and GT26 engines feature a unique sequential combustion system [1, 2]. This
system consists of a premixed combustor (called EV), which is followed by a high pressure …

Gas turbines are widely used as important equipment for electricity generation on islands
and offshore platforms. During the operation of a gas turbine, the flame shape in the …

Gas turbines that are used as compressor drives are often operated in the part load regime
because compressor stations are usually designed for operation with full power at extreme …
