Abstract

Performance of the PTTC propeller has been investigated numerically according to the instructions given in the Propeller performance -workshop of the SMP'11 symposium. The calculations have been performed by the RANS equation solver FINFLO. The workshop tasks included a prediction of the propeller open water curves, the propeller wake field, and the cavitation behavior at three different operation points. The model experiments were made for a validation of the calculations at the SVA Potsdam towing tank and the cavitation tunnel. The propeller wake field was captured reasonably but a denser grid should be created in order to reach a better grid convergence. The influence of a turbulence model should also be investigated. The cavitation predictions show a qualitatively reasonable behavior
