Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] FIG. 1 shows the construction method in accordance with an embodiment of the present invention at an arbitrary angle fitting.

[0017] FIG. 2 shows a comparison between a conventional angle fitting and an angle fitting according to an embodiment of the present invention.

DETAILED DESCRIPTION

[0018] FIG. 1 shows an arbitrary point at which the contour of a component transitions in a discontinuous manner from a first region 1 into a second region 2, wherein the two regions enclose an angle 3. At this point of discontinuity, substantial disturbances develop in the flow path, disturbances which can be strongly influenced by a suitably constructed geometric profile. Traditionally here, a so-called tube bend or a tube elbow is provided, which either provides a rounding with a selected radius or a sharp angle.

[0019] Based on various observations in nature, a method for forming the bend can be developed, said method being simple to construct and nevertheless influencing the flow conditions at the point of discontinuity in such a manner that the losses in the bend can be very greatly reduced with a minimum expenditure on construction and production. To this end, the angle bisector 4 of the angle 3 is constructed. A point 5 is selected on this angle bisector. Through this point 5, the straight lines 6 and 7 are taken perpendicularly to the regions 1 and 2. At point 5, straight lines which intersect regions 1 and 2, with the intersection point 11 being established in region 2, are taken at the angle 8 of 45° to these straight lines 6 and 7. The segment between the point 5 and the point 11 is bisected, yielding the point 9, at which a straight line is taken at the angle 10 of 22.5°, said line intersecting the region 2 at the point 13. The segment between the point 9 and the point 13 is again bisected, yielding the point 12, at which a straight line is taken at the angle 14 of 12.2°, said line intersecting the region 2 at the point 15. The envelope of this construction results in a contour.

[0020] The construction presented is based on an asymmetric loading of a component. If the component were loaded in a symmetrical manner, for example as a result of an alternating forward/return flow, then it would be possible to complement the construction in a symmetrical manner in the direction of the first region 1 in an analogous way.

[0021] FIG. 2 shows a direct comparison between an angle fitting having a conventional radius (right) and an angle fitting having a profile according to the invention (left). On account of its asymmetry, the profile according to the invention is to be installed in a fixed manner in one direction, to be specific such that the flow direction points from a first region 1 to a second region 2. In a direct comparison, the significantly smaller dimensions of the angle fitting according to the invention are noticeable. The simple construction according to the invention saves not only energy in deflecting the flow, but also installation space and material during the production of the angle fitting.

[0022] The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
