Abstract
A method of designing/making an acoustic side branch resonator structured to be coupled to a standpipe of, for example, a nuclear power plant, wherein the acoustic side branch resonator includes a plurality of wire mesh elements for damping purposes. The method includes determining a resonant frequency of the standpipe, determining an active length of the acoustic side branch resonator using the resonant frequency, and determining a particular number of the wire mesh elements to be used in the acoustic side branch resonator and a pitch of each of the wire mesh elements using momentum and continuity equations of a compressible fluid.
