“…The current BEM and FEM models have undertaken extensive numerical convergence and experimental validation experiments, which are described in Li et al [21][22][23]27 To further verify the present BEM codes, several examples are used. The steady pressure distributions of a three-blade propeller, namely the propeller 4119, are employed to assess the accuracy of the current approach for estimating the propellers' open-water performance.…”

“…Recently, the first author and coworkers have investigated the difference of these two different boundary conditions on the prediction of the hydroelastic performance of underwater rotating propellers. [21][22][23] Nevertheless, only the differences caused by the incoming velocity at the vibration position and the equilibrium position were discussed. The correction of the normal vector imposed on the deformed blade surface corresponding to the normal vector on the undeformed one is not taken into account.…”

This paper focuses on the development of a three-dimensional panel method in time and frequency domains combined with the finite element method for analyzing the hydroelastic responses of rotating marine propellers in the wake of ships. A fully non-penetration boundary condition imposed on the deformed blade surface is conducted, in which the corrections of both the incoming flow velocities and the normal vectors imposed on the deformed and undeformed blade surface are taken into account. The added-mass and -damping matrices due to strongly coupled fluid-structure interaction are considered. Results of the present method are compared with experimental data available in the literature. It is observed that the fully non-penetration boundary condition applied on the deformed blade surface should be imposed to predict the unsteady performance of elastic propellers, which is due to the change of the added damping predicted by considering different non-penetration boundary conditions.
