Ship Hydrodynamic propulsion: some contemporary issue of propulsive efficiency, cavitation and erosion

Topics ranging from the analysis of hull flows through to propeller design were considered in this paper, the purpose of which was to set a future research agenda and identify present shortcomings in knowledge. The interaction between measures to enhance efficiency and their possible consequences for cavitation development were explored, in terms of the potential for material erosion and in relation to ship vibration. Examination focussed on the practical application of these initiatives to ships on trials and in operational service. Additionally, a new conceptual method for detecting propeller erosion based on acoustic emissions was introduced.
