Abstract
A flow rectifier for mounting in a circular section duct conveying a fluid flow, the rectifier establishing two series of oppositely-rotating vortices in a ring, which vortices cancel one another, and are created by two series of angularly offset fins. The first series of fins is disposed uniformly around the inside surface of the ring while the second series of fins is disposed uniformly around a circumference centered on the center of the ring.
