Abstract

1. System for generating an artificial surge or swell in an ocean engineering experimental basin or dock, of the type having a beater constituted by a cylindrical float parallel to the rear wall of the basin, characterized in that the section of said float, i.e. the generatrix of said cylinder, has a substantially vertical rear side, i.e. substantially parallel to said rear wall, and a nose-shaped front side, and said float is associated with mechanical means imparting to it a horizontal alternating movement, the mean distance between the rear wall of the float and the rear wall of the basin being chosen in such a way that a resonance phenomen is created between the swell train produced by the oscillations of the water column between said walls and that created by the movement of the float, the superimposing of these two trains giving rise to a very high transfer function in a chosen swell period interval.

Claims

A device for generating artificial waves in an experimental tank for use in marine engineering of a type having an agitator formed by a cylindrical buoy parallel to the rear wall of the tank, wherein the cross section of the buoy, i.e. the cylindrical generator is generally vertical. That is, the wave generating device having a rear end generally parallel to the rear wall and a nose-shaped front end, wherein the float is connected to a mechanical device that transmits alternating horizontal movement.

2. The phenomenon of claim 1, wherein the average distance between the rear wall of the buoy and the rear wall of the tank is a resonance phenomenon between that generated by the movement of the buoy itself and the wave heat caused by the vibration of the water column between the walls. Wherein the overlapping of the two wave rows raises the transmission function very high during the selected wave period.

The wave generating device according to claim 1 or 2, wherein the rear portion of the buoy is slightly inclined forward from the vertical with the intention of eliminating flooding of water between the tank wall and the buoy.

The wave generating device according to any one of claims 1 to 3, wherein the device is installed in a wave and a flow tank.

An artificial wave generator suitable for a tank having a length of 30 m to 100 m, a width of 8 m to 33 m, and a depth of 0.5 m to 3 m, between the rear wall of the tank and the rear wall of the buoy. Has an average distance of 0.1 m to 2 m, an odd line width of the buoy is 0.5 m to 3 m, a nose-shaped angle α formed in front of the buoy is 15 to 90 degrees, and a depth of buoy 0.1 m to 2m, the movement of the sine curve imposed on the buoy is a period of 0.5 seconds to 4 seconds period, the wave generating device characterized in that the amplitude is 0.05m to 1.5m.
