Abstract
In this study, a large skewed propeller INSEAN E1619 model with 7 blades working in open water conditions has been numerically simulated by an inhouse URANS (Unsteady Reynolds-averaged Navier-Stokes) code coupled with dynamic overset grid approach. Grid and time-step sensitivity analysis of the propeller model has been conducted and the numerical results have been compared with available experimental data performed by INSEAN aimed to validate the numerical method. Propeller open water characteristics have been compared for models with different scales at given advance coefficient to evaluate scale effect of this high-skew propeller. Non-dimensional pressures on different scaled models have been compared between models with different scales. Results show that propeller’s thrust and torque increase with the increase of propeller scale, which is mainly due to the increase of pressure component. It could be found that the pressure on suction side near the trailing edge decreases with the increase of propeller’s scale.
