Description
The cross reference of related application
According to 35U.S.C. § 120, this application claims " the Surface Gravity submit, entitled on the 12nd of September in 2012
The rights and interests of the priority of Wave Generator And Wave Pool " U.S. Patent application 13/612,716, it is 2008
On November 19, in is submitting, entitled, and " the Surface Gravity Wave Generator And Wave Pool " U.S. is special
The part continuation application of profit application 12/274,321, the disclosure of priority application is incorporated herein by reference.
Technical field
The application is related to wave pool, and relates more particularly to at least one for the generation wave in wave pool
Fin and one or more passive type control machines for slowing down the mean flow in the wave pool as caused by fin, mutation and seiche
The wave pool of structure.
Background technology
Wave, which is used for being entertained, is up to the centuries.Most flowed at any seabeach of the breaker with excellent in shape
One of capable motion is surfing.Surfing and other aquaplanes have actually become such prevalence, so that being suitable for
The water surface near any broken sea that beats the shore of surfing is typically crowded and has born excessive surfer so that each surfer
Have to compete each wave and movable limited time.In addition, most of even without suitable machine in earth population
Wave can be contacted to enjoy surfing or other ocean wave motions.
Another problem is that wave in any place is all change and inconsistent, has " multigroup " satisfactory once in a while
Ground shaping, for people drive required for wave, wherein being studded with ripple that is more unacceptable, can not driving in some cases
Wave.Even when surfer tries to drive selected wave, the duration for multiplying wave averagely only lasts for only 2-30 seconds, greatly
Majority multiplies the unrestrained time between 5 to 10 seconds long.
Wave of the sea is the wave propagated along the interface between water and air, and restoring force is provided by gravity, therefore it
Be commonly referred to as surface gravity wave.Fig. 1 shows the principle for dominating the surface gravity wave for entering shallow water.Wave one in deep water
As have constant wavelength.When wave and seabed interact, it starts " shoaling ".Typically, this generation becomes in depth
When, wavelength also more shallow than the half of the wavelength of wave shortens and wave amplitude increases.When wave amplitude increases, because the crest of wave is moved
Must be faster than trough, so wave may become unstable.When wave amplitude is about the 80% of water depth, wave starts " to crush " simultaneously
And we obtain surf.This go up and shattering process depend on seabeach inclination angle and profile, wave close to seabeach angle,
And the depth of water and the characteristic of the deep water wave close to seabeach.By the change to bottom configuration, the refraction of these waves and concentration
It is possible.
Wave typically has five stages：Generation, propagation, aufhellung, broken and decline.Aufhellung and crushing stage are for that can drive
It is most desirable for rider wave.Break-up point not only depends strongly on the ratio between the depth of water and wave amplitude, and depending on the wheel in seabed
Wide, depth and shape.In addition, in other factors, speed, wavelength and the height of wave may also contribute to the broken of wave.
In general, wave can be described as causing four kinds of main broken sea types, this four kinds main broken sea types are：Collapse brokenly, volume is broken,
Collapse brokenly, and rolling is broken.In these wave types, begin to learn surfer and prefer to collapse breaker wave, and it is more experienced to roll up breaker wave
What surfer was worshipped.These broken sea types figure 2 illustrates.
Various systems and technology have been attempt to replicate wave in artificial environment.Some in these systems are included against reality
Waveform conducts fast motion, the relatively shallow sheet of water of figure modelling can be driven with the producing but actually not water of wave
Effect.Other systems are using oar, hydraulics or the pneumatic floating drum linearly activated or just with big controlled water injection
To produce actual wave.However, all these systems are all that efficiency is low in terms of " wave " is transformed energy into, and by
Neither one is gone back in a variety of causes and shortcoming, these systems and copies as people's driving close to such wave, the wave is produced
The required size of required optimal wave, shape, speed and broken, that is, what is collapsed brokenly enters volume shallow water, with tubulose
Broken wave, the wave has the face that relatively long duration and enough surfers are acted.

Big change, and allow the optimization of the shape of fin 500 to produce required shape of surging.This fine optimization is probably
It is required, because the other viscous fluid mechanical phenomenon fins for appearing in 500 surface work in boundary layer.Attachment
Boundary layer can have slightly change hydrofoil valid shape effect.In other embodiments, there can be specific surface
Roughness or " boundary layer trip " on hydrofoil surface.Particularly, if producing enough rapidss on restoring part
Stream is to ensure no flow separation, then the physical length of hydrofoil can reduce, and will not be so easily in unfavorable pressure
Strong turbulent boundary layer is isolated in power gradient.
In certain embodiments, based on the conversion from the simulation for the equation as the function of time to spatial function, the wing
Piece 500 shapes and is formed as special geometry.The stroke of piston is mathematically defined as time letter by hyperbolic tangent function
Number, to cause piston promotion wave-shape board to create the shallow-water wave propagated away from wave-shape board.These hyperbolic tangent functions relative to
Long wave produces the position that the wave position produced in model considers wave-shape board, and is produced for solitary wave and cnoidal wave
Acceptable profile.These technologies can be for producing the surface gravity wave of any propagation, and the surface gravity wave illustrates ripple
Wave (that is, is suitable for wave and how changed during generation) the reason for being propagated during generation away from generator.It is right
The compensation for the motion passed through over time in generator and the special shape of restoring part can help to remove the wave of oscillation of smearing, its
More compact and effective generating process can be provided.The other kinds of waves different from wave discussed here can be limited.
The thickness of fin may be relevant with the amplitude (height) of wave and the depth of water.Thus, for known depth and
Required amplitude A, can determine that the thickness of fin, FT, can be provided such as lower aprons：
For Rayleigh solitary wave：
For Bo Xinneisike (Boussenesq) solitary wave：
For shallow water, second order solitary wave：
Fig. 9 shows the cross-sectional geometry of fin 600.As three-dimensional body, speed of the fin 600 based on fin and
Vector VFProducing has spread speed and vector VWWave.When fin is moved along shown direction, depending on its speed, wave
It will be blazed abroad with peel angle α, regulation sin α=Fr- 1, therefore for the given depth of water and wave height, peel angle is by fin
Speed determines that larger speed corresponds to less peel angle.Peel angle is smaller, and the length of crest will just cross wave pool and get over
It is long.

Degree.These leads can also be integrated with azimuth flowing control and Redirectional system, as described in above-mentioned part.
Figure 23 shows that, by the time-evolution of the ripple obtained by mobile fin, it includes incidence wave and back wave is (more
It is individual).The wavelength for the ripple being incident on lead can be L.In some embodiments it may be desirable to make from the porous of lead
The percent reflectivity of the gained ripple of wall is optimized so that in rough approximation：
- a node (L/4) place porous wall=>0% (*) reflects, 100% (*) transmission.
- maximum (L/2) place porous wall=>100% reflection, 0% transmission.
If without perforated wall, node possibly be present at place with a distance from the rear wall L/4 from tank, and ceiling capacity loses
It possibly be present at this distance.However, due to the inertia resistance in porous wall, phase transformation possibly be present in gap, it can be with
Slow down ripple.This distance for ceiling capacity loss occur is less than L/4.As that can see in fig 23, the width of lead
