“…Moreover, in order to estimate the propeller side force that arise in oblique flow conditions, Ribner simplified theory has been implemented in the solver [27]. Further details on this approach are described in [28]. It has to be remarked that, in order to make the use of the open water curves consistent, the self-induction effect is properly accounted for by momentum considerations (axial-symmetric actuator disk theory) [29].…”

“…Multiple-rudder ships may have different starboard-side and port-side manoeuvring behaviours. The asymmetrical behaviours are notable for single-propeller twin-rudder ships (Hamamoto and Enomoto 1997;Hasegawa et al 2006b;Nagarajan et al 2009;Di Mascio et al 2011;Kang et al 2011;Broglia et al 2013). According to Yoshimura and Sakurai (1989), hydrodynamic characteristics of a twinpropeller twin-rudder are not so much different from those of a single-propeller single-rudder ship.…”

Rudders are primary steering devices for merchant ships. The main purpose of using rudders is to generate forces for course keeping and manoeuvring. In exceptional cases, rudders are also used for emergency stopping and roll stabilisation. Furthermore, rudders affect propeller thrust efficiency and total ship resistance. Therefore, rudders are important to navigation safety and transport efficiency. The performance of rudders depends on the rudder hydrodynamic characteristics, which are affected by the design choices. Scholarly articles concerning the design of rudders date back more than 60 years. Moreover, a lot of knowledge fragments of rudders exist in literature where ship manoeuvrability and fuel consumption are discussed. It is worthwhile to gather this information not only for researchers to advance the state-of-the-art development but also for designers to make proper choices. To have a contemporary vision of the rudders, this paper presents a consolidated review of design impacts on rudder performance in ship manoeuvrability, fuel consumption, and cavitation. The discussed design choices are rudder working conditions (Reynolds numbers and angles of attack), profiles (sectional shapes), properties (area, thickness, span, chord, and rudder aspect ratios), types (the position of the stock and the structural rudder-hull connection), and interactions (among the hull, the propeller, and the rudder). Further research is suggested on high-lift rudder profiles, multiplerudder configurations and interactions among the hull, the propeller, and the rudder. Recommendations for industry practices in the selection of the rudder design choices are also given.

“…The propeller performance is needed to establish the kinematic and dynamic models of HDUG (Nemati Hayati et al, 2013;Broglia et al, 2012). CFD method is then used to compute the hydrodynamic performance for the designed propeller.…”
