Abstract

The purpose of this study is to obtain the hydrodynamic characteristic of propeller in the oblique flow with various current angle (means oblique flow). The Reynolds-averaged Navier-Stokes (RANS) equations solver of the StarCCM+ software is employed with a realizable k-ε turbulent model. In the current study, the B-Series propeller (B:4-70) is used because of its use in commercial vessels. The simulation is conducted in two parts: at first, examination of propeller behavior in direct flow conditions and comparison with experimental conditions and in the next step analysis of the propeller in the oblique flow with angles of 10, 20, 30 and 40 degrees. The results are shown that the thrust and torque coefficients (KTx and KQx) are reduced by increasing the angle of flow and increasing the advance coefficient.
