Abstract

Economic pressures and regulatory requirements have brought about a great interest in improving ship propulsion efficiency. This can be exercised by installing Energy Saving Devices (ESD) such as Propeller Boss Cap Fins (PBCF) . This paper demonstrates an approach for optimising PBCF by using Computational Fluid Dynamics (CFD) analysis. The conducted CFD open water model tests were validated by comparison with experimental data until the simulation was deemed satisfactory within the capabilities and limitations of the model. A design and optimisation procedure was defined to analyse the impact of ESDs on propeller efficiency and then used to evaluate the different geometric parameters and locations of the PBCF on the hub. This analysis was done at full scale using high fidelity CFD - based RANS methods. Outcomes of the study include a design and optimisation process that can be used for the analysis of other ESDs on the market. The influences of varying the geometry of the PBCF were examined with optimal solutions presented for the analysis case. The impact on the regulated Energy Efficiency Design Index (EEDI) and ESD savings were then discussed along with the influences on the energy efficiency.
