Abstract
A high-performance rectifying device promotes the diffusion of energy, temperature and concentration in a fluid stream with a small pressure loss. The device is a lattice type rectifying device provided within a fluid flow passageway for equalizing the flow velocity distribution of the same fluid. Lattice elements each consist of two triangular plates disposed so as to form two opposed surfaces of a pyramid having its apex on the downstream side of the fluid flow and two other triangular plates forming two opposed surfaces of another pyramid having its apex jointed with the first-mentioned apex and having its bottom surface positioned on the downstream side of the fluid flow. The latter two opposed surfaces have their orientations deviated by 90 degrees from the two opposed surfaces on the upstream side. The lattice elements are arrayed in juxtaposition in directions perpendicular to the fluid flow with the orientation of adjacent lattice elements deviated by 90 degrees from each other and are connected in such a manner that the bottom surfaces of the above-mentioned pyramids may form a lattice. Furthermore the ratio of the length, in a direction parallel to the flow, of the lattice element to the breadth, in the direction perpendicular to the flow, of the lattice element should be kept in a range of 1.5-2.0. The lattice element may also be formed of a rectangular plate twisted by 90 degrees in the direction along the direction of the fluid flow.
