Experiments on the structure of turbulence in a wall subchannel of a rod bundle (P/D = 1.07)

Description

Measurements of the distributions of the mean velocity, the wall shear stresses and the turbulence were performed in a wall subchannel of a rod bundle of four parallel rods (P/D = W/D = 1.07). The Reynolds number of this investigation was Re = 8.528 x 104. The experimental data showed, that the measurements performed earlier in this geometry are reproducible. Therefore, the statements especially on the anisotropy of the eddy viscosities are valid. (orig.)

Abstract (German)

An einem Stabbuendel aus vier parallelen Staeben wurden in einem Wandkanal (P/D = W/D = 1.07) die Geschwindigkeits-, Wandschubspannungs- und Turbulenzverteilungen gemessen. Die Reynoldszahl der Untersuchung betrug Re = 8.528 x 104. Die Messergebnisse zeigten, dass die frueheren Messungen an der gleichen Geometrie sehr gut reproduzierbar sind. Daher sind die Aussagen insbesondere im Hinblick auf die Anisotropie der Wirbelviskositaeten belastbar. (orig.)
