Abstract: A device and method for reducing swirl in a gas compressor is provided. The device can include a tubular or annular seal body having an abradable interior surface for use in forming a seal. The tubular body can further have a plurality of swirl teeth arranged on a high pressure side of the seal body. The swirl teeth are disposed so as to form swirl slots between the adjacent swirl teeth. The swirl teeth can have a brake chord and a brake pitch describing the length and separation of each adjacent swirl tooth. The ratio of the brake pitch to the brake chord can be optimized in order to maximize creation of free vortices between the swirl teeth as the compressor rotates for swirl reduction.
