• A surface panel method to analyze the hydrodynamic properties of a ducted propeller operating in uniform flow is described. The present method solves the problem of an impeller and a duct simultaneously. It is an extension of the potential-based low-order surface panel method for the analysis of open propellers developed by Hoshino. Further, a new wake model for the trailing vortex wake of the ducted propeller is proposed, based on the accurate measurement of flow field by a 3-component Laser Doppler Velocimeter(LDV). The present method can predict the pressure distribution over ducted propeller in detail. And the open-water characteristics of a ducted propeller calculated by the present method show a better agreement with experimental data.
