A pool wave, as created in a wave pool, typically works through the displacement of water using a large, submerged foil or similar device.
Here's a breakdown of the process:
- The Device: A large submerged foil, often shaped like a snowplow or wedge, is positioned at one end of the pool.
- Towing Mechanism: This foil is attached to a cable or other mechanical system that tows it along the bottom of the pool.
- Water Displacement: As the foil moves through the water, it pushes the water forward, creating a displacement wave. This wave propagates outwards across the surface of the pool.
- Continuous Wave Generation: By repeatedly towing the foil back and forth or using multiple foils in a coordinated manner, a continuous series of waves can be generated.
- Wave Shaping (Optional): Some wave pools incorporate additional features to shape and control the waves, such as contoured pool bottoms or strategically placed barriers.
In simpler terms, imagine pushing a large plate through the water in your bathtub. The water in front of the plate is displaced, creating a wave that travels outwards. Wave pools operate on the same principle, but on a much larger scale.
