Abstract
A stackable noise attenuating disk includes an inner perimeter edge and an outer perimeter edge. A plurality of inlet passages is disposed along the inner perimeter edge and a plurality of outlet passages disposed along the outer perimeter edge. The plurality of outlet passages includes first outlet passages having a first width and second outlet passages having a second width, which is greater than the first width. Each of the plurality of outlet passages defines a longitudinal axis that is offset by a predetermined angle from a radial axis extending through a corresponding outlet passage. The plurality of inlet passages and the plurality of outlet passages are arranged such that fluid entering one of the plurality of inlet passages exits through at least one of the plurality of outlet passages.
