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

The heat release distribution, combustion instability characteristics and flow dynamics of
lean swirl-stabilized flames of hydrogen enriched natural gas were studied using time …

Numerical simulation of a dual-swirl gas turbine model combustor is performed under cold
and reacting flow conditions using a three-dimensional unsteady Reynolds-averaged Navier …

We report on the experimental study of a precessing vortex core (PVC) in an air model of a
Francis turbine. The focus is placed on the modal decomposition of the PVC that occurs in …

In a centrally-staged combustor, the stratified swirling flame often manifests a helical mode,
which is characterized by the emergence of helical vortices, including the precessing vortex …

This work investigates the influences of precessing vortex cores (PVCs) on the coherent
interactions in the transient flow and heat release fields of a weak premixed swirling flame …

Global instabilities in swirling flows can significantly alter the flame and flow dynamics of
swirl-stabilized flames, such as those in modern gas turbine engines. In this study, we …

The flame transfer functions (FTF) is a key quantity to assess the thermoacoustic properties
of combustion systems. It is known to depend on the hydrodynamic instabilities of the …

Effects of secondary gas injection on flame shape and combustion stability of a premixed
swirl methane/air flame were investigated experimentally. Without secondary gas injection …

This study introduces the Extended Cluster-based Network Modeling (eCNM), a
methodology to analyze complex fluid flows. The eCNM focuses on characterizing dynamics …
