Abstract:   (4925 Views)

In this paper a computational method is presented for predicting the unsteady hydrodynamic forces acting on partial immersed propeller (SPP). In order to simulate the unsteady viscous flow around a SPP, a Reynolds-Averaged Navier–Stokes (RANS) solver is used. The time-accurate calculations are made by applying the sliding mesh method. Structured and unstructured mesh techniques are used. The method is applied in the case of the straight condition. Hydrodynamic coefficients are compared with experimental data and show good agreement between them. Also, ventilation pattern, pressure distribution and unsteady forces/moments on key blade of SPP is presented and discussed.

Keywords: Partial immersed propeller, RANS method, Sliding mesh, Unsteady forces/moments
