Stability analysis of thermo-acoustic nonlinear eigenproblems in annular combustors. Part II. Uncertainty quantification
Monte Carlo and Active Subspace Identification methods are combined with firstand second-order adjoint sensitivities to perform (forward) uncertainty quantification analysis of the thermo-acoustic stability of two annular combustor configurations. This method is applied to evaluate the risk factor, i.e., the probability for the system to be unstable. It is shown that the adjoint approach reduce...
متن کاملMitigating Combustion-driven Oscillation (Thermoacoustic Instability) in Industrial Combustors
Combustion processes generate a band-limited pseudo-random sound that is often referred to as “combustion roar.” Although combustion roar sound is moderately intense but it is rather straight forward to quiet to a non-objectionable level by properly applying sound absorbing material around the burner area. In addition to the 'roar' sound which almost always exists in any confined combustion, on...
متن کاملThermoacoustic Instabilities: Modelling and Control
The goal of this study was twofold. First, modelling strategies were proposed to characterize the dynamics driving the thermoacoustic instabilities in a swirl-stabilized premixed burner. Secondly, this model was used to synthesize controllers in order to apply active control strategies to suppress this phenomenon. An experimental combustor model based on acoustic properties of the combustion ch...
متن کاملAcoustic streaming measurements in annular thermoacoustic engines.
Experiments with an annular thermoacoustic engine employing quasiadiabatic interaction between traveling acoustic waves and an inhomogeneously heated porous material indicate the presence of a closed-loop mass flux. A qualitative modeling of the enthalpy flux in the thermoacoustic core provides an opportunity to estimate the thermal convection associated with this mass flux, by using temperatur...
متن کاملModeling and Active Control of Thermoacoustic Instabilities
Due to stringent emission regulations, modern gas turbines work in lean premixed mode and thermoacoustic instabilities are often observed. They cause mechanical damage and therefore have to be reduced. This paper describes the development of an acoustic network model for a lab-scale lean premixed methane combustor at ETH Zurich. The model is verified against experimental data and is then used t...
