Combustion instabilities can lead to dire and costly consequences to the heat engines if not properly dealt with. Helmholtz resonators are widely used passive acoustic dampers to attenuate acoustic pressure waves arise from instabilities. However, their effectiveness is limited to a narrow frequency...
