Abstract:
A device for enhancing uniformity of fluids within a moving fluid stream within the confines of a conduit, said conduit being characterized as having a substantially circular cross section, a longitudinal axis, a fluid inlet and a fluid outlet, said device comprising a core pipe located at the approximate longitudinal axis of said conduit, said core pipe acting as a mandrel for the application of least first and second layers of vanes, said first layer of vanes being helically wound about said core pipe, the inner diameter of said first layer of vanes being substantially co-extensive with the outer diameter of said core pipe wherein each of said vanes of said first layer being of substantially constant angle to said longitudinal axis and said second layer of vanes being helically wound about said first layer of vanes such that said second layer of vanes have an inner diameter substantially co-extensive with the outer diameter of said first layer of vanes and the vanes of said second layer being of a substantially constant angle to said longitudinal axis, the sign of each layer of vanes being opposite to adjacent layer of vanes so that interstices are created between adjacent layers of vanes which are substantially constant along the length of said core pipe.
