The combustion noise produced by a confined, turbulent, premixed swirl burner is predicted
with large-eddy simulation of compressible, reacting flow. Characteristics-based state-space …

In this work, results of comprehensive high-pressure tests and numerical simulations of high
momentum jet flames in an optically accessible combustion chamber are presented. A …

A method for selective, frequency-resolved analysis of spatially distributed, time-coherent
data is introduced. It relies on filtering of Fourier-processed signals with periodic structures …

Scale Adaptive Simulations (SAS) of the swirl-stabilized flame of the PRECCINSTA burner
are presented. Within the computations a large share of velocity fluctuations as well as …

The computation of low Mach number self-excited thermoacoustic instabilities using large
eddy simulations requires an efficient compressible, multi-species, reacting flow solver …

The computation of self-excited thermoacoustic instabilities remains a challenging task.
Reasons are manifold as the problem renders itself as a complex interplay of mixing …
