Abstract: Thermoacoustic properties of can-annular combustors are commonly investigated by means of single-can test-rigs. To obtain representative results, it is crucial to mimic can–can coupling present in the full engine. However, ...

Abstract: A strut injector for burning hydrogen has been optimized using an automated workflow system. In order to choose the optimal set of injectors to cover the design space, an optimized design of experiments (DOE) method was ...

Abstract: Heavy-duty land-based gas turbines are often designed with can-annular combustors, which consist of a set of identical cans, acoustically connected on the upstream side via the compressor plenum, and, downstream, with a ...

Abstract: Thermoacoustic systems can exhibit selfexcited instabilities of two nature, namely cavity modes or intrinsic thermoacoustic (ITA) modes. In heavyduty landbased gas turbines with canannular combustors, the crosstalk between ...

Abstract: The intrinsic thermoacoustic (ITA) feedbackloop constitutes a coupling between flow, flame and acoustics that does not involve the natural acoustic modes of the system. One recent study showed that ITA modes in annular ...
