Abstract

In this paper PIV-Measurements are presented for a Y-bifurcator of a power plant. The
Plexiglas model test consists of a 42 degree bend, a straight pipe from the bend to the Y-branch and two branching pipes with a branching angle of 40 degrees. At several locations PIV-Measurements upstream and downstream of the Y-bifurcator are carried out by using natural seeding particles. The quality of the seeding particles will be presented by means of the velocity lag and the size of the particles. A confidence interval for a typical PIV-Measurement is calculated to demonstrate the reliability of the mean velocity. The result of the PIV-Measurement shows the velocity profile and the secondary flow within the Plexiglas installation. The secondary flow will also be quantified by the velocity correction factor α. Due to the reflection at the Plexiglas surface, the velocity profile will be closed with a linear function. The accuracy of this procedure will be checked with a CFD calculation.
