Benefits of technology

The present invention provides a structure and method for reducing the drag of a ship by installing turbulence generators on the hull to generate beneficial turbulence and delay the separation of the boundary layer, which increases the pressure of the aft part of the hull and speeds up the ship. This leads to a reduction in fuel consumption and navigation time. The structure includes at least one turbulence generator installed between the widest section and the aft end of the hull or on the bottom surface between the deepest portion and the aft end.

Problems solved by technology

Ship suffers the drag while sailing which slow down the speed of ship.
The drag causes not only more fuel consumption, but also wear down the motor and the transmitting mechanism, as well as produces more exhaust gas and longer time to complete the voyage.
The environmental pollution, extra fuel consumption and time loss to the transportation field are inevitable.
Although the streamlining of the shape of ship's hull is helpful to reduce drag, but the effect is still limited.
The difference of the longitudinal pressure also causes the drag to the ship.
Accordingly, aforesaid various kinds of drag are detrimental to the ship's speed.

embodiments

[0035]In order to lay out the above and other purposes, features and advantages of the present invention more explicitly, the embodiments described herein are incorporated by the accompanying drawings for the detailed description.

[0036]Referring to FIGS. 2 and 3, the variation and the effects of the current when it encounters the turbulence generator of the present invention is described as follows. As shown in FIG. 2 and FIG. 7, a turbulence generator 2 installed on the hull 100 of a ship 1 comprises an impact surface 21 facing the incoming flow of water for colliding with and generating turbulence when the flow collides with the impact surface 21. Current C has a relative velocity with the turbulence generator 2 when the ship 1 sails in the water. As shown in FIG. 2, when the current C flows pass through the turbulence generator 2 with an attack angle A, more turbulence V will be induced behind the turbulence generator 2 when the current C collides with the turbulence generator 2....

Abstract

A structure for reducing the drag of a ship and its application thereof is provided. The structure for reducing the drag of a ship comprising at least one turbulence generator which is installed on the side surface between the widest section and the aft end or on the bottom surface between the deepest portion and the aft end of the ship. The arrangement of the turbulence generator can generate turbulence to reduce the drag of the ship, and thereby increase the speed of the ship or reduce fuel consumption as well.

Description

1. FIELD OF THE INVENTION[0001]The present invention relates to the structure of a ship and its application thereof for reducing drag of the ship while sailing, particularly to a ship having a turbulence generator on the surface of the hull for generating turbulence to reduce drag of the ship and its application thereof.2. DESCRIPTION OF RELATED ART[0002]Ship suffers the drag while sailing which slow down the speed of ship. The drag causes not only more fuel consumption, but also wear down the motor and the transmitting mechanism, as well as produces more exhaust gas and longer time to complete the voyage. The environmental pollution, extra fuel consumption and time loss to the transportation field are inevitable.[0003]Although the streamlining of the shape of ship's hull is helpful to reduce drag, but the effect is still limited. Referring to FIGS. 1A and 1B, a perspective view of a conventional ship sailing in the water is shown. The ship 1 comprises a hull 100. The direction of s...
