The measurement data is recorded using a five-hole probe. These are used to record the magnitude and direction of the velocity vector at a local point within a flow field. A miniature five-hole probe with a spherical head is used. The probe head has a diameter of 2 mm and the pressure holes each have a diameter of 0.3 mm. The measurements were carried out at a Mach number of 0.13.
Extraction modules enable controlled steam extraction, for example to feed a district heating network, while at the same time reducing the turbine output generated. Depending on the set operating point, however, these extraction modules can have a sensitive effect on the surrounding flow field and cause time-dependent and highly asymmetrical component loads. Within the planned project, these operating point-dependent flow fields are to be experimentally measured and analyzed within a generic extraction module. With the help of the experimental measurement results on the generic model, the numerical findings are to be verified and examined with regard to their general validity. and If you are interested in the measurement data please contact andreas.schramm@rub.de
