PCT No. PCT/SE82/00301 Sec. 371 Date May 27, 1983 Sec. 102(e) Date May 27, 1983 PCT Filed Sep. 29, 1982 PCT Pub. No. WO83/01290 PCT Pub. Date Apr. 14, 1983.A flow distributor capable of forming a defining wall of a duct or chamber having further defining walls comprises a profiled, apertured plate. The plate is provided with profile sections or wall sections which extend transversally of the direction of the main flow immediately downstream one or more apertures. The profile sections form baffle means for dividing the main flow of medium into a plurality of part flows and for deflecting said part flows through respective apertures to the opposite side of said defining wall. Located between the profile sections are substantially planar, apertured sections which extend in parallel with or are inclined to the direction of the main flow, while forming an arrangement of step-like or shoulder-like protrusions. Alternatively, the plate may exhibit adjacent one or more of said apertures corrugations which curve inwardly or outwardly towards and away from said flow, a part of which corrugations forms said profile sections. |
