PROPULSOR MODEL TESTS IN CAVITATION TUNNEL

As a part of a Business Finland funded research project, VTT is seeking to conduct model tests for ship propulsor. Key aspect is to study the cavitation behaviour of the propulsor and thus the tests will be conducted in a model test facility with a cavitation tunnel. The propulsor is a cycloidal type propeller. VTT will provide the model size propulsor for the tests. The main dimensions and description and requirements for model testing are described in more detail in the invitation to tender documents. Model test facility providing the cavitation tunnel should provide at least thrust and sideforce measurement for the propulsor, as well high speed camera footage showing the cavitation behavior. VTT personnel and third party research partners should be able to take part in the tests and operate the model device. VTT will prepare the official test program.
