Abstract: Experiments are carried out on the laboratoryscale MICCASpray annular combustor to examine the effects of swirlers on combustion instabilities. This system comprises 16 sprayswirl injectors and gives rise to instabilities ...

Abstract: Acoustic transfer matrices are widely used in the analysis of combustion dynamics of gas turbines. The reliability of the analysis thus depends on the quality of the determination of the transfer matrices of the individual ...

Abstract: The quality of liquid fuel spray injection determines to a large extent the performance of aero-engine combustors. This investigation focuses on the detailed characterization of the liquid fuel spray in a test rig targeted ...

Abstract: Recent investigations of combustion instabilities in annular systems indicate that considerable insights may be gained by using information gathered in singlesector experiments. Such experiments are, for example, employed ...

Abstract: Combustion instability in annular combustors of jet engines is a recurring issue. In this study, the characteristics of instabilities for different fuels are investigated by combining the instability maps obtained in a ...
