Journal Article
Wang, J., Rubini, P., Qin, Q., & Houston, B. (2019). A model to predict acoustic resonant frequencies of distributed Helmholtz resonators on gas turbine engines. Applied Sciences, 9(7), 1419. https://doi.org/10.3390/app9071419

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 that of a single neck h... Read More
