Integrated air foil and diamond flow vane
A flow enhancing arrangement for ducts such as rectangular flue ducts wherein a series of tear shaped foils are spacedly mounted in the duct extending from top to bottom thereof and where a series of diamond shaped vanes also extending from the top to the bottom of the duct are spacedly mounted between the tear shaped foils to provide a more uniform flow distribution and to lower the pressure thereby. A series of baffles extending from both the tear shaped foils and the diamond shaped vanes may also be used.
1 . A flow enhancing arrangement for ducts having fluid flow therein comprising:
a series of tear-shaped foils spacedly extending across the duct; and
a series of diamond shaped vanes shapedly extending between said series of tear-shaped foils.
2 . A flow enhancing arrangement for ducts as set forth in claim 1 including a series of baffles extending from said tear shaped foils and from said diamond shaped vanes.
3 . A flow enhancing and arrangement for ducts as set forth in claim 2 wherein said tear-shaped foils have a rounded end and a sharp end and wherein said baffles extend from said rounded end of said foils.
4 . A flow enhancing arrangement for ducts as set forth in claim 1 wherein said diamond shaped vanes have sharp front and back ends and said baffles extend from said front end.
5 . A flow enhancing arrangement for ducts as set forth in claim 1 wherein said tear-shaped foils have a rounded end and a sharp end and wherein said baffles extend from said rounded end of said foils.
6 . A flow enhancing arrangement for ducts as set forth in claim 5 wherein said diamond shaped vanes have sharp front and back ends.
7 . A flow enhancing arrangement for ducts as set forth in claim 5 wherein the duct is a rectangular flue duct.
