Thermoacoustic combustion instability is one of the most challenging operational issues in
several high-performance, low-emissions combustion technologies, including gas turbines …

This study investigates the linear stability of a laminar premixed flame, anchored on a
square cylinder and confined inside a channel. Many modern linear analysis concepts have …

The dynamics of an axisymmetrical swirling jet is studied via global linear stability and
resolvent analyses. The modeled flow represents a combustor-like swirling jet, that is …

This paper investigates the amplification and propagation of swirl fluctuations in turbulent
swirling flows using resolvent analysis. Swirl fluctuations have been repeatedly observed in …

The flow field of the swirl-stabilized combustor plays a significant role in fuel atomization and
flame stability. The experimental investigation of the non-reacting flow field downstream of a …

Operation under stable conditions is an important prerequisite for gas turbine safety. While
recent studies have focused primarily on acoustic design to avoid thermoacoustic …

The next generation of gas turbines must enable partial or pure hydrogen combustion to
decarbonize electricity production. In this respect, jet burners have received increased …

The thesis aims to apply recent developments of methodology from the field of linear
instability theory to the study of combustion instability. The flame instability here refers to the …

Inflow perturbations are imposed on an axisymmetric, enclosed, turbulent, non-parallel, and
compressible swirling flow, for which the swirler is modelled and included in the numerical …

Operation under stable conditions is an important prerequisite for gas turbine safety. While
recent studies have focused primarily on acoustic design to avoid thermoacoustic …
