Abstract:
Waves are generated on the surface of a body of water, at regular intervals, by a wave generator in which water is periodically lifted and allowed to fall in a water-lift chamber. Water enters and leaves the lift chamber through an underwater opening at its bottom. It is lifted by drawing a vacuum in the top of the lift chamber and dropped by releasing that vacuum. Air is periodically exhausted from the lift chamber to create a vacuum therein by an air blower through an air buffer having a series of interconnected air chambers, to minimize air-pressure fluctuations at the air blower intake. Vacuum in the lift chamber is periodically released by opening it to the atmosphere.
