Combustion instability remains a critical issue limiting the development of low-emission,
lean-premixed (LPM) gas turbine combustion systems. The present work provides a …

Combustion dynamics constitutes one of the most challenging areas in combustion
research. Many facets of this subject have been investigated over the past few decades for …

Combustion instability has become a major issue for gas turbine manufacturers. Stricter
emission regulations, particularly on nitrogen oxides, have led to the development of new …

In many continuous combustion processes, such as those found in aeroengines or gas
turbines, the flame is stabilized by a swirling flow formed by aerodynamic swirlers. The …

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

Analysis of combustion instabilities relies in most cases on linear analysis but most
observations of these processes are carried out in the nonlinear regime where the system …

Nine decades of rocket engine and gas turbine development have shown that
thermoacoustic oscillations are difficult to predict but can usually be eliminated with …

Combustion noise is becoming increasingly important as a major noise source in
aeroengines and ground based gas turbines. This is partially because advances in design …

Transfer functions of premixed laminar flames submitted to incident flow perturbations are
envisaged and a unified model is derived analytically. This model, based on a linearization …

This paper describes an experimental investigation of acoustically forced lean premixed
turbulent bluff-body-stabilised flames in an enclosure short enough so that no coupling of …
