Advanced Model Experiment for the Research of Journal Bearings with Cavitation 2019-01-2331
The prediction of cavitation in journal bearings is one of the current challenges in the field of fluid dynamics. Hydrodynamic journal bearings are used in a wide range of industrial applications because they provide low friction and minimal wear. Suction cavitation is one potential cause of bearing failures. The work on hand presents a new experimental approach to study suction cavitation in a scaled bearing model. Moreover, mechanical and fluid dynamic similarity laws are described which enable the transfer of bearing operation conditions into the laboratory experiment.
