- In this paper, numerical results, based on implicit LES andtransport equation mass transfer modelling approach, submitted to the Second International Workshop onCavitating Propeller Performance at the Fourth InternationalSymposium on Marine Propulsors (SMP’15) are presented.The numerical simulations are performed usingOpenFOAM. The present work is focused on the secondtask of the workshop, Propeller in oblique flow insidetunnel in wetted and cavitating conditions. We summariseresults from the three different operating conditions given in the task, where the experimental data of one condition isrevealed, and the two other conditions are put forward asblind tests to workshop participants. For the conditionwhere experimental data is known, we see good agreementfor the forces in wetted conditions that slightly deteriorate in cavitating conditions. Cavitation extent is over predicted, where mid-span bubbly cavitation in the experiments is predicted as a sheet cavity; cavitation in the tip region does however seem reasonable. This is also likely the reason for the larger error in force prediction. A limited mesh resolution study has been performed.
