Example
• For í µí± = 1í µí± , the maximum actuator stroke is about 0.25í µí±.
• For í µí± = 2í µí± , the maximum actuator stroke is 0.5í µí±.
VII.4. Conclusion
In conclusion, this chapter provides an overview of 2D wave flume analysis and synthesis. The
focus is on the problem of wave propagation, specifically studying the flap-type wavemaker
configuration for precise wave generation. The mathematical model is presented, which includes
the Laplace equation and various boundary conditions governing the velocity potential and wave
behavior. The perturbation method is employed to approximate solutions for the first-order wave
generation problem. The synthesis of the wave flume is discussed, considering its dimensions
and limitations such as wave break limit, maximum wave height, ballscrew acceleration, and
actuator stroke. The dispersion relation is solved iteratively to determine the wave number
corresponding to each period of interest. Finally, the maximum allowable actuator strokes are
determined for different wave periods. Overall, this chapter provides valuable insights into the
theory and practical aspects of wave flumes.
