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. http://pubs.sciepub.com/marine/6/1/3/marine-6-1-3.pdf hydrodynamic characteristics b-series propeller oblique flow StarCCM+
