Generation of Arbitrary Wave Field in Arbitrarily Configured Wave Basin Composed of Element-absorbing Wavemakers

摘要

The mathematical formula for deriving the motion of element-absorbing wavemakers closely installed on the circumference of an arbitrarily configured wave basin is proposed, with the aim of generating an arbitrary wave field in this basin. This formula was obtained through the asymptotic expansion of the Hankel function for large arguments. Numerical and experimental results of wave heights of long-crested regular waves obtained in the elliptic basin have clarified that the proposed mathematical formula can provide a long-crested regular wave field at a distance longer than at least a single wavelength from the wavemakers.
