| Zusammenfassung | This article contributes shortly to the results of the previous studies concerning installation disturbances. The experiments are not finished yet, so that the results are preliminary. The initial measurements on this topic had been carried out on the test rig of the Fernwärme Wien company under the direction of Karlheinz Lechtermann and also on the old test rig at the BEV by F. Adunka, starting in 1996. By the end of 1998 the BEV had built up its new test rig for measurements with a very low uncertainty [1,2]. Additionally a Laser-Doppler-Velocimeter (LDV) was purchased by which axial flow profiles after disturbances could be studied. Moreover, the flow profile development in the lines of test rigs could be examined thus giving valuable data on the influence of disturbances on meters under test. The presented results had been published in extracts in [3] and [4], recent measurements on the BEV test rig have been published partly, too (see [4] - [9]). The measurements of this article are a sum of most recent findings, but they are - as mentioned above - preliminary. |
