Bifurcation Analysis of Self-excited Thermoacoustic Oscillations in Damper-equipped Combustion Chambers
This paper presents the stability and bifurcation analysis of a nonlinear thermoacoustic model consisting of a combustion chamber coupled to a Helmholtz damper. Only the acoustic mode in the cavity of the combustion chamber to which the Helmholtz damper is tuned is considered. The Helmholtz damper includes a non-smooth damping term and can be seen as a tuned vibration absorber with a coupling o...

متن کاملExcited-state thermodynamics
In the last several years, the Casimir energy for a variety of 1+1-dimensional integrable models has been determined from the exact S-matrix. It is shown here how to modify the boundary conditions to project out the lowest-energy state, which enables one to find excited-state energies. This is done by calculating thermodynamic expectation values of operators which generate discrete symmetries. ...
متن کاملForced and self-excited oscillations of an optomechanical cavity.
We experimentally study forced and self-excited oscillations of an optomechanical cavity, which is formed between a fiber Bragg grating that serves as a static mirror and a freely suspended metallic mechanical resonator that serves as a moving mirror. In the domain of small amplitude mechanical oscillations, we find that the optomechanical coupling is manifested as changes in the effective reso...
