Commissioning of a test rig for the investigation of laminar annular gap flow

Masterthesis, Bachelorthesis
Two unique test rigs are operated at the FST for the dynamic characterization of flow through annular gaps, such as those used in fuel pumps in the aerospace industry (e.g. Ariane 5 launch vehicle). As part of the work, one of the two test rigs, the test rig for investigating laminar annular gap flow, is to be expanded, put into operation and used to investigate the dynamic properties of the annular gap flow in the transitional region between laminar and turbulent flow.

Identifikation der dynamischen Eigenschaften durchströmter Axialschubentlastungseinrichtungen
Identification of the dynamic characteristics of axial thrust balancing devices

Masterthesis, Bachelorthesis
The dynamic behaviour of modern turbomachinery, such as those used in fuel pumps in the aerospace industry (e.g. Ariane 5 launcher), is largely determined by the dynamic properties of combined axial and radial annular gaps. These annular gaps are primarily found in axial thrust balancing devices in centrifugal pumps. To date, however, the dynamic influence of these machine elements is largely unknown. For this reason, a worldwide unique test rig was built at the FST, which will be put into operation in this thesis.
