The motivation of the present study is to contribute to the knowledge of partial submerged propellers (PSPs) in the search for a reliable performance prediction method with regard to the ventilation flow around PSPs using a hybrid grid-based Reynolds-averaged Navier–Stokes (RANS) solver. To achieve accurate results and obtain the correct behaviour extraction of the ventilation zone, a fine mesh was generated around the propeller and the free surface. The hydrodynamic coefficients of the PSP, the ventilation pattern and other results were calculated for a range of advance coefficients. The predicted ventilated open-water performance of the PSPs as well as the ventilation shape are in good agreement with the experimental measurements and observations. Finally, discrepancies between the numerical results and the experimental data are quantitatively evaluated in terms of the relative percentage error for the PSP characteristics.
