Wave pool and wave generator for bi-directional and dynamically-shaped surfing waves
A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.
1. A wave generator for generating a wave in a pool of water and having bi-directionality, the wave generator comprising:
a foil having a vertical front surface and a vertical back surface, the vertical front surface defined by a proximal edge, a distal edge, a bottom edge and a top edge, the vertical front surface being substantially symmetrical around a central vertical axis between the proximal edge and the distal edge to provide substantially equal respective first and second wave forming surfaces, each of the first and second wave forming surfaces having a horizontal cross-sectional geometry that is concave about a front vertical axis in front of the vertical front surface thereof between a point defined by the respective proximal or distal edge and a midsection of the foil, the central vertical axis comprising a pivot bearing around which the foil pivots according to a yaw angle, the foil having rotation in the yaw angle about the central vertical axis to at least a first position and a second position, each of the first and second positions forming a leading surface of one of the first and second wave forming surfaces, and forming a trailing surface of the other of the first and second wave forming surfaces, the rotation to the first or second position enabling the leading surface to exert drag against the water when the foil moves in a horizontal direction perpendicular to the central vertical axis to generate a primary wave in the pool, and enabling the trailing surface to decrease the drag of the leading surface to minimize oscillatory waves that trail the primary wave from the water that moves past the leading surface; the vertical back surface having a V-shape including a vertex, a first back side and a second back side, the vertex facing outward about the central vertical axis,
wherein the first back side extends toward the proximal edge to form a leading back surface and the second back side extends toward the distal edge to form a trailing back surface in the first position, and wherein the first back side forms the trailing back surface and the second back side forms the leading back surface in the second position.
2. The wave generator in accordance with claim 1 , wherein the leading back surface is vertically oriented to be substantially parallel to the horizontal direction in the first position or the second position.
3. The wave generator in accordance with claim 1 , further comprising a bottom plate extending down from the bottom edge of at least one of the first and second wave forming surfaces.
4. The wave generator in accordance with claim 1 , further comprising a top plate extending up from the top edge of at least one of the first and second wave forming surfaces.
5. The wave generator in accordance with claim 1 , further comprising a top surface and a bottom surface, and wherein the vertical front surface, vertical back surface, the top surface and the bottom surface form a three-dimensional container.
6. The wave generator in accordance with claim 5 , wherein the three-dimensional container includes one or more compartments.
7. The wave generator in accordance with claim 6 , wherein the one or more compartments includes one or more water or air fillable sections for buoyancy control of the foil.
8. The wave generator in accordance with claim 7 , wherein the one or more compartments includes one or more water-filled sections, and wherein each water-filled section includes one or more apertures for water flow therethrough.
9. The wave generator in accordance with claim 1 , wherein the yaw angle is tunable to achieve one of a number of generated waves.
10. The wave generator in accordance with claim 1 , wherein the foil is further configured to generate a right breaking wave and a left breaking wave in response to traversal of the foil along a track, the foil further configured for bi-directional movement along the track.
11. The wave generator in accordance with claim 1 , wherein the pivot bearing comprises a post connected with a bogie.
12. The wave generator in accordance with claim 1 , wherein the foil comprises one or more actuators configured to push or pull opposing sides of the foil and lock the foil into a desired yaw angle.
