Deterministic quantities characterizing noise driven Hopf bifurcations in gas turbine combustors

N Noiray, B Schuermans - International Journal of Non-Linear Mechanics, 2013 - Elsevier
Lean premix gas turbine combustors are prone to high amplitude pressure oscillations
driven by non-linear thermoacoustic coupling. These pulsations are unwanted because they …

Combustion noise: modeling and prediction

CKW Tam, F Bake, LS Hultgren, T Poinsot - CEAS Aeronautical Journal, 2019 - Springer
