RISModel-Based Inference of Flame Transfer Matrices From Acoustic Measurements in an Aero-Engine Test Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flame dynamics, represented as a flame transfer matrix (FTM), is not directly measurable in test rigs and must be deduced from transfer matrix measurements of the combustion system. The burner-flame transfer matrix (BFTM) ...
The Nonlinear Thermoacoustic Eigenvalue Problem and Its Rational Approximations: Assessment of Solution Strategies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonlinear eigenvalue problems (NLEVPs) arise in thermoacoustics by considering the temporal evolution of small perturbations in the relevant governing equations. In this work, two solution strategies are compared: (i) a ...
