ABSTRACT:
An acoustic resonator apparatus for efficiently transmitting acoustic energy from a plurality of acoustic transducers to a fluid passing through a cylindrical shell. A plurality of pairs of acoustic transducers are mounted on the cylindrical shell, each transducer of a pair being 180.degree. away from the other transducer of the pair, and each pair being associated with another transducer pair which is disposed 90.degree. away from such pair. Each of the transducer pairs is excited with energy of the same frequency and magnitude, but transducer pairs which are disposed 90.degree. from each other are excited with energy which is out of phase by 180.degree..
