A module and modular apparatus for efficiently producing waves in a body of water
This invention relates to apparatus for the energy-efficient production of non-turbulent waves in a body of water and capable of producing a discrete wave or a succession of waves having a repetition rate and size that is suitable for surfing. The wave-making apparatus comprises a plurality of wave-making modules arranged side by side in parallel in a body of water (5) having an opposing beach (4) on which the waves may break. Each wave-making module comprises a reservoir (2) and a piston (1), the piston suspended so as to be able to move freely in a horizontal direction within the reservoir. Waves are generated in the body of water by the withdrawal (6) and forward (7) motions of the piston 1 when driven by an actuator. The design of the apparatus makes use of the resonant cavity that is formed between the piston (1) and the back wall of the reservoir (9), and makes use of the otherwise wasted wave energy from the withdrawal stroke of the piston, when reflected from the back wall of the reservoir (9), to supplement the forward, wave-generating stroke of the piston and thereby produce large non-turbulent waves with a high energy efficiency that are suitable for surfing and recreation. By energizing each wave-generating module in a sequence from one end to the other avoids the very high power requirement that would result from their simultaneous activation.
