General information on our generating waves

Resonance

The majority of « classical » waves generators  (pistons, water tanks or fans) consume a lot of energy. Moreover, they create a wave which is lifted and definitely lost after being injected into the pool. In opposite, WOW generators use intelligently all energy of the stretch of water for an impressive result!  Their working mode based on the resonance is managed by a computer software which take the pool configuration and environment changes into account, as for example the fluctuations in the number of swimmers.

The WOW generators create a first wave on water which is spread in the pool. Once reflected by the walls (freeboards), the wave comes back to the generator. The computer management system controls permanently the required power to amplify (or decrease) the waves produced.

Pool characteristics

The pool characteristics will have an influence on the waves generator’s efficiency. To choose an adapted generator, you have to take into account :

• The Freeboards quality (part of the wall above the water) : the ideal freeboard is smooth and vertical. Its size will determine the maximum wave that can be generated without overflow. The following rule is applied to value the possible size of the waves :
  maximum wave possible = freeboard * 1,5
  
  
• The pool area : it will of course have an influence on the required power of the machine, on its capacity to generate sufficient wave to reach the edge of the pool and to come back in order to amplify.
   
• The depth : for each type of generator and sometimes for each model, a minimum depth is determinated. It’s a security depth (if Wave Ball) or simply bound to the efficiency of the machine working.
   
• The openings such as beaches, stairs are elements which prevent or slow down the return of the wave. They thus reduce the efficiency of the generator and conversely involve an over-sizing machine in order to obtain the required power in order to generate requested waves.
   
• The filtration : the kind of filtration used can have an impact on waves quality.
  • The overflow : it’s incompatible with the creation of waves.
  • The wall conduits : their position must be studied with WOW
