Abstract:
1. A duct having a flow deflector arranged therein, the flow deflector comprising a first member and second member, in which either of said first and second member has a geometry selected from concave, convex, planar, planoconcave, plano-convex and combinations thereof, and in which said first and second members intersect and form an angle α of 30° to 150° with respect to each other, the first member is provided with an aperture that defines an inner perimeter on said first member, said inner perimeter of the first member corresponds to the perimeter of the second member, and said second member intersects said first member through the aperture and at intersection points on the first member located along a line joining two directly opposing points of the inner perimeter of the first member, and wherein the duct is formed by inner and outer ducts in which the space inside the inner duct defines an inner region for the passage of a fluid and the space between the inner and outer ducts defines an annular region for the passage of the fluid, the first member intersects said annular region and extends across said annular region at an angle α/2 with respect to the length axis of the duct until contacting the outer duct along the perimeter of the first member, the second member intersects said inner region and extends across said inner region until contacting the inner duct along the perimeter of said second member.
