Abstract
A flow modifying device comprises an outer shell, a central tube within an interior space of the outer shell, and a plurality of helix vanes within the interior space. The central tube extends along at least a portion of a length of the outer shell. Each of the helix vanes extend along the outer shell and along the central tube. An outer edge portion of each of the helix vanes is attached to the outer shell and an inner edge portion of each of the helix vanes is located within a central passage of the central tube. In this manner, a first portion of each of the helix vanes extends between the outer shell and the central tube and a second portion of each of the helix vanes is located within the central passage of the central tube.
