Abstract
Hull-engine-propeller matching is one of the key issues of ship design. It plays an important role in improving the economy and safety of ship navigation. The hull-engine-propeller matching is generally based on the Factory Acceptance Test of engine and the Sea Acceptance Test of ship. These conventional methods cost money and time. To overcome these defects, this paper proposes a simulation method based on the quasi-steady model of engine and CFD for ship hydrodynamics to study the interaction among the hull, engine and propeller, which provides the basis for ship-engine-propeller matching. Taking the PA6 diesel engine and the ONR tumblehome ship as the study objects, the quasi-steady model of engine is constructed by using simulation software and applied to carry out simulation under the operation conditions; the ship resistance test, propeller open-water test and self-propulsion test are simulated by using CFD method. Based on the simulation results, an integrated simulation platform is established for studying the hull-engine-propeller interaction. Further, the external characteristics of diesel engine under the effects of hull-engine-propeller interaction are predicted for the ship sailing straight ahead at different speeds. This paper provides a new method for studying the characteristics of hull-engine-propeller interaction.
