Lattice Boltzmann simulation on the flow behaviour associated with Helmholtz cavity-backed acoustic liners

Noise from jet engines can be reduced by means of a Helmholtz cavity configuration. The resonance that occurs when a flow passes the neck of the Helmholtz resonator will dissipate acoustic energy. The mechanism for such dissipation is mainly due to the vortex shedding that occurs at the neck of the...
