The current study examined the self-excited thermoacoustic instability of hydrogen/methane
premixed flames using a variable-length combustor (300–1100 mm). The global dynamic …

The current research aims at studying the effect of using biomass-derived syngas as a
supplement of the natural gas in a microturbine. The study includes microturbine …

This paper describes an experimental investigation of the nonlinear response of a premixed
methane/air low-swirl flame to imposed acoustic excitation with perturbation amplitude up to …

The current work examines the excitation of thermoacoustic instability of lean premixed
hydrogen-methane/air low swirl flames under both atmospheric and elevated pressure …

Gain and phase are two key characteristics of flame transfer function (FTF) in evaluating
unsteady flame response. Few studies have investigated the correlation between gain and …

This experimental study explored the influence of global/local flame behaviors on direct
combustion noise produced by a lean-premixed gaseous H 2/air low-swirl turbulent jet …

In this work, we propose an analytical decomposition of the flame transfer function (FTF) in
the complex space. The decomposition provides new insight into the relationship between …

Chemical composition of synthetic gas and concentration of its components depend on
gasification process and feedstock. Synthetic gas mainly consists of hydrogen (H2) and …

The current research focuses on the thermoacoustic instability of lean premixed combustion,
which is a promising technique to inhibit Nitrogen Oxides (NOx) emission. Thermoacoustic …
