© 2019 by the authors. Helmholtz resonators, traditionally designed as a narrow neck backed by a cavity, are widely applied to attenuate combustion instabilities in gas turbine engines. The use of multiple small holes with an equivalent open area to... Read More about A model to predict acoustic resonant frequencies of distributed Helmholtz resonators on gas turbine engines.
