Title: APPARATUS FOR IMPROVING HYDRODYNAMIC CONDITIONS WITHIN A CONDUIT

Abstract

An improved header is designed for eliminating the phenomena of boundary growth, boundary separation, and boundary flow reversal within a divergent passageway having an equivalent cone angle greater than 20 deg . The header is disposed at the inlet end of an annular divergency and adapted to distribute a rotational fluid flow across that inlet end. Vane means are mounted adjacent the inlet end to establish within the divergent passageway a solid body rotation having both a rotational component of fluid velocity and an axial component of fluid velocity in the direction of the divergence. The vane means are so constructed as to direct a substantial portion of the inlet flow toward both walls of the divergence and a drag ring on the bottom of the vanes will cause a substantially greater portion of the inlet flow to be directed toward one wall than toward the other wall of the annuiar passageway to eliminate any defects which were not eliminated by solid body flow.
