This is a comprehensive, critical, and pedagogical review of volumetric emission
tomography for combustion processes. Many flames that are of interest to scientists and …

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

The dynamics of hydrogen-enriched partially premixed methane–air flames are investigated,
focusing on the frequency response to velocity and equivalence ratio fluctuations. Large …

The present study combines Large Eddy Simulation (LES) with System Identification (SI) to
determine the Flame Transfer Functions (FTFs) of technically premixed flames that respond …

In this study, the acoustics and flame dynamics of a prototype multi jet burner with 19
individual mixing tubes for operation with pure hydrogen and pure natural gas are …

Equivalence ratio fluctuations have been identified as a major driving mechanism for
thermoacoustic instabilities in lean premixed combustion. In the present study, equivalence …

A measurement technique for determination of the global and local equivalence ratios from
the flame chemiluminescence for a swirl-stabilized lean premixed combustion of natural gas …

The synchronization process between the fuel-feeding excitation (ff) and the local
equivalence ratio (ϕ local) is a key issue that has not been well studied numerically under …

Predicting thermoacoustic instabilities in annular combustors requires knowledge of the
impact of acoustic oscillations on heat release rate oscillations. Flame Describing Functions …
