Abstract:An analysis is made of the tonal acoustic radiation produced by nominally steady, low Mach number flow past a shallow, rectangular wall cavity in the presence of a cross-beam in the flow adjacent to the cavity. At 'lock-on' the frequency of vortex shedding from the beam is equal to one of the resonant frequencies of the cavity. The sound produced by this vorticity is augmented by the presence of the cavity and is calculated for the lowest order resonance frequency of the cavity by using a Green's function deri… Show more
