“…The height ratio of the mesh sizes is 1.4 in Domain 3. Layer meshes are required for simulating turbulence, especially at high Reynolds numbers (Wang, Su, Wang, Zhu, & Liu, 2014 Zhu & Fang, 2012), the thickness of the first prismatic layer mesh shown in Figure 6c is set to 0.0001D with a stretching factor of 1.10. There are 10 prismatic layers, and the total thickness of prismatic layers is 0.4 mm.…”

“…A mismatching hub can decrease the propulsive efficiency and cavitation performance significantly. In recent years, computational fluid dynamics (CFD) techniques have been employed more and more extensively for analyzing the performance of hydrodynamic systems (Carlton, Radosavljevic, & Whitworth, 2009;Carrica, Fu, & Stern, 2011;Dubbioso, Muscari, & Mascio, 2014;Lam, Hamill, & Robinson, 2013;Lam, Robinson, Hamill, & Johnston, 2012;Shamsi, Ghassemi, Molyneux, & Liu, 2014), designing propeller ESDs (Çelik, 2007;Lee, Bae, Kim, & Hoshino, 2014;Park, Jung, & Kim, 2005) and simulating the cavitation (Rafael et al, 2015;Singhal, Athavale, Li, & Jiang, 2002;Watanabe, Kawamura, Yoshihisa, Maeda, & Rhee, 2003;Zhu & Fang, 2012). The International Towing Tank Conference (ITTC) discussed applications of the CFD method to calculating the hydrodynamic performance of propellers and believed that it could be used to obtain the open-water performance and pressure distribution of a propeller accurately (Salvatore, Streckwal, & Terwisga, 2009).…”

This paper presents the simulated and experimental results of propeller-rudder systems with propeller boss cap fins (PBCFs) and analyzes the hydrodynamic performance of PBCFs in propellerrudder systems. The purpose is to study the impact of PBCFs on the hydrodynamic performance of rudders. Hydrodynamic experiments were carried out on propeller-rudder systems with PBCFs in a cavitation tunnel. The experimental energy-saving effect of the PBCF without a rudder was 1.47% at the design advance coefficient J = 0.8. The numerical simulation was based on the Navier-Stokes equations solved with a sliding mesh and the SST (Shear Stress Transfer) k-ω turbulence model. After the grid independence analysis, the flow fields of an open-water propeller with and without a PBCF were compared, then the efficiencies of the propulsion systems including different rudders and the thrust coefficient K r of rudders were analyzed. The results indicate that the installation of a PBCF increases the resistance of the rudder, which results in a reduction in the energy-saving effect of the PBCF. At the design advance coefficient, the energy-saving effect of the PBCF with an ordinary rudder and a twisted rudder decreases from 1.47% to 1.08% and 1.16%, respectively; thus, it is important to factor in the rudder of a propulsion system when evaluating the energy-saving effects of PBCFs .

“…A proper specification of propeller design is required to make sure the propeller can produce a driving force to move the ship forward in the most effective ways [1,2]. Other than that, improper propeller design and specification have a direct influence on the reduction of propeller performance and fuel efficiency of the ship propulsion system [3,4]. The configuration of the propeller becomes a typical discussion among the naval architectures because the selection of the proper propeller design depends on the specification of the vessel and it also affects the manufacturing cost.…”

A reliable prediction approach to obtain a sufficient thrust and torque to propel the ship at desired forward speed is obviously required. To achieve this objective, the authors propose to predict the thrust coefficient (KT), torque coefficient (KQ) and efficiency (η) of the propeller in open-water model test condition using Computational Fluid Dynamics (CFD) simulation approach. The computational simulation presented in the various number of rotational speed (RPM) within the range of advance ratio J=0.1 up to 1.05. The higher value of J leads to a decrease in 10KQ and KT. While the η increased steadily at the lower value of J and decreased at the higher value of J. The results also showed that the propeller with 1048 rpm obtains a better efficiency at J=0.95 with η= 88.25%, 10KQ=0.1654 and KT= 0.0942. The computation result is very useful as preliminary data for propeller performance characteristics.
