operating conditions and the water quality. However, due to the very good stability and repeatability of the CEIMM tunnel, it was possible to directly relate the nuclei distribution with the cavitation inception characteristics, and to transpose the results to an accurate unique “zero tension” bucket, that defines the own propeller behavior under the actual test configuration. This result is very important, but further studies will be conducted in order to confirm it and to examine its influence on the full-scale characteristic bucket.
Several vain attempts have been made for many years to try to compare similar tests carried out in different facilities, but this new approach looks promising.
The authors wish to acknowledge first the Italian Navy and the French Navy, who agreed in working together on this subject.
The authors wish to acknowledge all the colleagues from the CEIMM, and specially the staff of the cavitation tunnel, for their enthusiastic participation during the tests campaigns.
This work is supported financially by the Italian Navy and the DRET, that the authors wish to acknowledge more particularly.
