The dynamic transition from combustion noise to combustion instability was investigated experimentally in two laboratory-scale turbulent combustors (namely, swirl-stabilized and …
Thermoacoustic instability in turbulent combustors is a nonlinear phenomenon resulting from the interaction between acoustics, hydrodynamics, and the unsteady flame. Over the …
Thermoacoustic instability, also known as combustion instability, continues to be a problem in the development of modern gas turbine combustors and rocket engines. Such instability is …
