“…Moving reference frame provides a faster and an efficient way to simulate thrusters such as ship propellers. The method is widely used in numerical open-water propeller simulations [18]. In a recent article, moving reference frame is used extensively to estimate the self-propulsion parameters for a bulk carrier [19].…”

Estimation of ship self-propulsion is important for the selection of the propulsion system and the main engine so that the ship can move forward with the required speed. Resistance characteristics of the vessel or the open-water performance of a propeller only are not usually enough to assess the working conditions of the ship. Both in numerical simulations and in experiments; there is a need to treat the propulsion system and the hull as a whole for a better estimation of the self-propulsion parameters. In this study, the self-propulsion points of one submarine (DARPA Suboff) and two surface piercing vessels (KCS and DTC) were obtained with methods based on computational fluid dynamics (CFD) approach. The self-propulsion points were also calculated by a classical engineering approach that makes use of the empirical relations that may be found in the literature. The results were evaluated with respect to the experiments and numerical results generated by other researchers in this field. It was found that the self-propulsion points of traditional ship forms can be very closely approximated with a classical engineering approach, given the basic geometric and the hydrostatic properties of the hull and the propeller.

“…In addition to this area, the important results of simulating, analyzing and optimizing the characteristics of a marine propeller were presented by Hu J. et al, (2017), Lin Y. et al, (2017) and Wang Z. et al, (2012), [7][8][9]. The obtained results in the studies on effects of geometry configuration on hydrodynamic performances of a propeller proposed the innovative way to design propeller including effects of wake flow and skew angle on propeller's features [10][11][12][13]. The other authors got effects of the rudder shape on propeller's hydrodynamic characteristics in the propeller-rudder system [14,15] from which they suggested the useful way to improve hydrodynamic performances of the propeller.…”

In this work, the commercial Computational Fluid Dynamics (CFD), ANSYS-Fluent V.14.5 has been used to illustrate the effects of rudder and blade pitch on hydrodynamic performances of a propeller. At first, the characteristic curves of a container ship propeller are computed. Then, effects of rudder on hydrodynamic performances of the propeller in the both cases of the propeller with and without rudder have been investigated. The relationships between the blade pitch angle and the hydrodynamic performances of the selected referent propeller in this work having designed conditions as diameter of 3.65 m; speed of 200 rpm; average pitch of 2.459 m and the boss ratio of 0.1730. Using CFD, the characteristic curves of the marine propeller, pressure distribution, velocity distribution around propeller and the efficiency of the propeller have been shown. From the obtained results, the effects of rudder and blade pitch angle on hydrodynamic performances of the propeller have been evaluated.
