Cavitation by spall fracture of solid walls in liquids [PDF]
, 2014 Experiments are carried out to investigate the cavitation process induced by the spill-off from material from a surface in a liquid environment. Therefore, a simplified physical model was designed which allows the optical observation of the process next ...

A new methodology for hydro-abrasive erosion tests simulating penstock erosive flow
IOP Conference Series: Earth and Environmental Science, 2016 Hydro-abrasive resistance is an important property requirement for hydroelectric power plant penstock coating systems used by EDF. The selection of durable coating systems requires an experimental characterization of coating performance. This can be achieved by performing accelerated and representative laboratory tests.

Hydro-abrasive erosion: Problems and solutions
IOP Conference Series: Earth and Environmental Science, 2014 The number of hydro power plants with hydro-abrasive erosion is increasing worldwide. An overall approach is needed to minimize the impact of this phenomenon. Already at the start of the planning phase an evaluation should be done to quantify the erosion and the impact on the operation.
