Abstract
A gas compression apparatus and method according to which an impeller rotates to flow fluid through a casing, and a plurality of vanes are mounted on a plate in the casing. A series of cells are formed in the plate to form an array of acoustic resonators to attenuate acoustic energy generated by the impeller.
Claims21
A gas compression apparatus comprising a casing having an inlet for receiving gas;
- an impeller disposed in the casing for receiving gas from the inlet and compressing the gas;
- a plate disposed in a wall of the casing;
- a plurality of vanes extending from the plate;
- and a plurality of cells formed in the plate to form an array of resonators to attenuate acoustic energy generated by the impeller.
A method of attenuating noise in a gas compression apparatus in which an impeller rotates to flow fluid through a casing and a plurality of vanes are mounted on a plate in the casing, the method comprising forming a plurality of cells in the plate to form an array of resonators to attenuate acoustic energy generated by the impeller.
