This paper reviews recent advances in understanding the structure of turbulent partially
premixed and stratified flames. The term “partially premixed” refers here to compositionally …

The goals of the present review paper are;(i) to introduce experimental facilities and
numerical tools applied to investigating inhomogeneously premixed flames,(ii) to summarize …

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

Swirl burners are widely used in aeronautical engines and industrial gas turbines. These
burners enhance the flame stabilization by bringing back hot products to the reactive zone …

In the present work, a direct numerical simulation (DNS) of an experimental high Karlovitz
number (Ka) CH 4/air piloted premixed flame was analyzed to study the inner structure and …

A key challenge in the transition towards using hydrogen as an alternative carbon-free fuel
is the reduced thermal radiation due to the absence of soot. A novel solution to this may be …

Intense strain, turbulence, heat transfer, and mixing with combustion products can affect
premixed flames in practical combustion devices. These effects are systematically studied in …

In this study, a novel strained, non-adiabatic flamelet generated manifold (FGM) model is
developed based on a counterflow premixed flame. The different levels of strain and heat …

Flames propagating through a mixture with a gradient of equivalence ratio have been
previously demonstrated to travel faster or slower than their equivalent premixed flames. The …

Pilot flames are commonly used to extend combustor operability limits and suppress
combustion oscillations in low-emissions gas turbines. Combustion oscillations, a coupling …
