Anwendung eines Volumenresonators (Helmholtz-Resonators) zur Pulssationsdämpfung

The Helmholtz resonator principle can be used by adding a volume in a side branch. The fluid in the volume and its connecting line form a resonant subsystem. Only pulsation waves at frequencies below the particular resonant frequency of the resonator can be attenuated by this arrangement. No useful attenuation effect is gained at higher frequencies [1].
