Thermoacoustic oscillations associated with transverse acoustic modes are routinely
encountered in combustion chambers. While a large literature on this topic exists for rockets …

This paper presents recent progress in the field of thermoacoustic combustion instabilities in
propulsion engines such as rockets or gas turbines. Combustion instabilities have been …

Thermoacoustic phenomena generated inadvertently during combustion, and those
produced by heating and cooling material to generate a temperature gradient, have mostly …

Progress in analytical methods to predict and control azimuthal combustion instability
modes in annular chambers | Physics of Fluids | AIP Publishing Skip to Main Content …

The influence of the injection system on combustion instabilities is investigated on a
laboratory-scale combustor equipped with a single injector that is weakly-transparent to …

Rotationally symmetric annular combustors are of practical importance because they
generically resemble combustion chambers in gas turbines, in which thermoacoustically …

The objective of this paper is to develop an analytical model to capture two symmetry
breaking effects controlling the frequency and nature (spinning, standing or mixed) of …

Thermo-acoustic instabilities in gas turbine engines are studied to avoid engine failure.
Compared to the engines with annular combustors, the can-annular combustor design …

Many physical problems containing rotating symmetry exhibit azimuthal waves, from
electromagnetic waves in nanophotonic crystals to seismic waves in giant stars. When this …

A non-premixed methane/air flame under a transverse acoustic mode is studied by
combining theoretical analysis and numerical simulations to understand the acoustic and …
