Abstract
The hydrodynamic performance of ships can be improved by the retrofit of Energy Saving Devices (ESDs). These devices are typically seen in the aft part of the ship hull and act by lowering the ship resistance, conditioning the fluid in front of the propeller and/or recovering energy from the rotational swirl of the fluid leaving the propeller. Technological gaps in the field suggested that there is a room for the development of a new biomimetic ESD based on ‘tubercles’ technology. Tubercles are rounded structures naturally found on the leading edge of the Humpback’s whale flipper and they are capable to hydrodynamically control the flow around the whale. Similarly, a novel device has been created to control the flow around the aft part of the hull, reducing ship’s resistance and improving the wake conditions in which the propeller operates. This research paper presents tubercles technology, working principles and the results from the first numerical experiments of a full-scale ship fitted with the created tubercled ESD. The results from this investigation revealed a promising potential of this novel technology.
