Stability, sensitivity and optimisation of chaotic acoustic oscillations

22 Nov 2019 Huhn Francisco Magri Luca

In an acoustic cavity with a heat source, such as a flame in a gas turbine, the thermal energy of the heat source can be converted into acoustic energy, which may generate a loud oscillation. If uncontrolled, these nonlinear acoustic oscillations, also known as thermoacoustic instabilities, can cause large vibrations up to structural failure... (read more)
