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 …

Since its birth in the 1920s, quantum mechanics has motivated and advanced the analysis of
linear operators. In this effort, it significantly contributed to the development of sophisticated …

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 …

Reducing the footprint of greenhouse gases and nitrogen oxides (NOx) emissions from
combustion systems means that they have been operating under lean or ultra-lean fuel–air …

Thermoacoustic instability in turbulent combustors is a nonlinear phenomenon resulting
from the interaction between acoustics, hydrodynamics, and the unsteady flame. Over the …

Accurate prediction of limit cycle oscillations resulting from combustion instability has been a
