Linear diffraction and radiation of surface waves by a hollow suspended cylindrical shell

Conference Paper


Abstract


  • A first-order analytical solution for the diffraction and radiation

    of ocean surface waves around a suspended hollow cylindrical

    shell is presented. We revisit the problem first studied by

    Garrett (1970), using a new and more direct technique to obtain

    the solution for the wave potential. Numerical results are

    presented for the combined diffraction and radiation problems,

    showing the wave field inside and around the structure. The

    results give fundamental insight into both the ideal design and

    placement of an Oscillating Water Column (OWC) device in the

    ocean, so as to extract the maximum possible energy from an

    incident plane wave field.
