Abstract

A noise reduction device for fluid flow systems comprises an inner section and an outer annular section. The inner section and the outer annular section has apertures on both upstream and downstream sides. The total cross-sectional area of the downstream apertures of the outer section is less than the total cross-sectional area of the downstream apertures of the inner sections. The device also includes a fin downstream of the downstream apertures of the inner section and of the downstream apertures of the outer section and between the inner section and the outer section. The fin facilitates separation between fluid flow from the inner section and fluid flow from the outer section.
