WORKSHOP I
Assessment of material resistance to cavitation: current experience and state of the knowledge

proposed topics:

What existing erosion test techniques can be recommended for industrial applications?
Mean Depth of Penetration or Cumulative Volume Loss: which parameter is to be used
when comparing results obtained under different cavitation conditions?
If the Mean Depth of Penetration parameter is still to be used then how to evaluate the damage area?
Instantaneous or cumulative volume loss (depth of penetration) rates: which of them are to be used?
What is the value of single-number parameters?
Experience on the water quality and synergy effects

WORKSHOP II

Material resistance to cavitation: new concepts and research trends

proposed topics:

Cavitation erosion test standards: test methods and material assessment procedures.
Recommendations on standardisation policy.
Volume loss end erosion curve models: do any chances for unification exist?

Compatibility between cavitation resistance assessments basing on tests at various facilities:
new concepts.
Assessment of cavitation intensity and prediction of material performance under field conditions;
new concepts and research trends
