Abstract

PURPOSE: To increase wake gain and improve propulsive efficiency in such a way that knuckle shaped bends to generate separation of the water flow along the hull are formed at the bilge part from the maximum cross-sectional areal position of a twin-screw vessel up to the central position of the propeller shafts at the stern.
CONSTITUTION: In the shape at the stern on two axial lines having screw propellers at the symmetrical position to the hull central line, knuckle shaped bends 15 to generate separation of the water flow along the hull are formed within the range surrounded by the span 16 from the central position 13 of the propeller shafts up to the lower ship's bottom line 14 and the span 17 from the central position of the propeller shafts up to the lowest end of the bilge part a little to the board on the body line in the maximum cross-sectional area of the ship. Separation of flow is generated at the knuckle bends, to generate a three-dimensional longitudinal eddy, by which frictional wake coming from the upstream is rolled on the propeller surfaces to increase wake gain and to improve the propulsive efficiency.
