In the analysis of combustion instabilities, especially for the longitudinal modes, the flame
typically is regarded as a discontinuity at rest and the flame motion is usually ignored …

Thermoacoustic instability in the combustion chamber of gas turbines, aero and rocket
engines has become a topic concern. In this paper, a new instability phenomenon in the …

Variable-thrust cryogenic propellant rocket engines are gaining significant research interest
in space exploration. However, low-frequency unstable combustion is still a challenging …

In this paper, the Background-Oriented Schlieren (BOS) technique is used to measure the
temperature field of a laminar conical premixed propane-air flame. Thermocouples and OH …

Thermoacoustic instability is a major issue in aero-engine and gas turbine combustion
chambers, especially for the case of lean premixed combustion. The instability is caused by …

Indirect combustion noise, as an important source of noise in gas turbines, was traditionally
attributed solely to entropy waves. In recent years, compositional waves were introduced as …
