Wave simulator for board sports
View Patent ↗Examples of a wave simulator for board sports and other uses are disclosed. An example wave simulator includes means for forming a wave, the means having at least one inclined side wall and a bottom corresponding to a desired wave shape. The wave simulator includes means for flowing water along at least partially along the inclined side wall and bottom of the flume to form a simulated wave. The wave simulator includes means for restraining a board rider in the means for forming a wave. Streamlines of the simulated wave are substantially parallel to a crest line of the simulated wave, and an inclined water flow ends in a downward arc.
1. A wave simulator comprising:
a container for pressurizing water pumped therein; and
an aperture positioned on a surface of the container that is formed to extrude a simulated wave shape;
wherein the aperture extrudes a simulated wave from the container along an open channel such that a crest of a simulated wave is extruded at the aperture at a point higher than the lower portion of the simulated wave;
wherein the aperture extrudes an entire profile of the simulated wave instantaneously from the aperture.
2. The wave simulator of claim 1 , further comprising a removable faceplate, and water flows out of the removable faceplate.
3. The wave simulator of claim 2 , further comprising a plurality of apertures on the removable faceplate, wherein each of the plurality of apertures have a removable cover so that the plurality of apertures can be covered and uncovered to extrude different simulated waves from the removable faceplate.
4. The wave simulator of claim 2 , wherein a portion of the removable faceplate is contoured and shaped, relative to a flat plane, whereby properties of the simulated wave can be varied.
5. The wave simulator of claim 1 , wherein the aperture is formed substantially in a shape of an obtuse triangle, wherein a side of the obtuse triangle that is located between two acute angles of the obtuse triangle is convex-shaped such that its midpoint is closer to an obtuse angle of the obtuse triangle than if the side of the obtuse triangle is a straight line.
6. The wave simulator of claim 5 , wherein the obtuse angle of the obtuse triangle shape of the aperture is adjacent a bed of the open channel.
7. The wave simulator of claim 1 , wherein the aperture is substantially triangle shaped, wherein at least one side of the triangle shaped aperture is convex-shaped such that its midpoint is closer to a base of the triangle than if the side of the triangle is a straight line.
8. The wave simulator of claim 7 , wherein the base is adjacent a bed of the open channel.
9. The wave simulator of claim 1 , wherein the aperture is substantially shaped as a right triangle, wherein a hypotenuse of the right triangle is convex-shaped such that its midpoint is closer to the right angle of the triangle than if the hypotenuse was a straight line.
10. The wave simulator of claim 9 , wherein a right angle of the right triangle is adjacent a bed of the open channel.
11. The wave simulator of claim 1 , wherein the open channel is shaped relative to a horizontal plane such that the open channel has a bend along its length, and at least one sidewall of the open channel is curved along the bend.
12. The wave simulator of claim 1 , wherein the container has a similar shape as the aperture.
13. The wave simulator of claim 1 , further comprising means to guide the flow of water in the container prior to the water being extruded from the aperture.
14. A wave simulator comprising:
a vessel for pressurizing water pumped therein;
an aperture positioned on a surface of the vessel that is formed to extrude a simulated wave shape;
wherein the aperture extrudes a simulated wave from the vessel along an open channel such that a crest of a simulated wave is extruded at the aperture at a point higher than the lower portion of the simulated wave;
wherein the aperture extrudes an entire profile of the simulated wave instantaneously from the aperture; and
a larger body of water possessing a free surface that is adjacent the open channel.
15. The wave simulator of claim 14 , wherein the open channel has at least one sidewall having an upper edge and at least one opposite sidewall having a lower edge, the at least one lower edge of the channel submerged in a larger body of water to share a common free surface, and at least a portion of the bed of the open channel is located below the free surface.
16. The wave simulator of claim 14 , further comprising a second lower edge of the open channel located substantially at a second end of the open channel downstream from a first end of the open channel.
17. The wave simulator of claim 14 , wherein water from the larger body of water is pumped into the vessel and through an aperture for extrusion.
18. The wave simulator of claim 14 , further comprising a first aperture on a first half of a faceplate and at least a second aperture on a second half of the faceplate.
19. The wave simulator of claim 18 , wherein the second aperture has a similar shape as the first aperture.
20. A wave simulator comprising:
means for pressurizing water pumped therein; and
means for extruding a simulated wave shape through an aperture positioned on a surface of the means for pressurizing;
wherein the aperture extrudes an entire profile of a simulated wave from an aperture such that a crest of a simulated wave is extruded at the aperture at a point higher than the lower portion of the simulated wave.
