Thermoacoustic instability is a flow instability that arises due to a two-way coupling between
acoustic waves and unsteady heat release rate. It can cause damaging, large-amplitude …

The unsteady response of a flame to acoustic or flow perturbations plays a crucial role in
thermoacoustic combustion instability. The majority of studies on this subject presents and …

Accurate prediction of limit cycle oscillations resulting from combustion instability has been a
long-standing challenge. The present work uses a coupled approach to predict the limit …

Combustion noise comprises two components: direct combustion noise and indirect
combustion noise. The latter is the lesser studied, with entropy noise believed to be its main …

The present article investigates the interactions between the pilot and main flames in a novel
stratified swirl burner using both experimental and numerical methods. Experiments are …

A coupled numerical approach is investigated for predicting combustion instability limit cycle
