Unsteady theory of the hydrofoil of finite span

  • Lu Chuanjing
  • He Yousheng


A three-dimensional unsteady flow around the hydrofoil has been dealt with in this paper. Under the assumption of infinitesimal wave and thin hydrofoil, analytic solution of perturbation velocity potential induced by the unsteady flow of a hydrofoil which is simplified as a series of rectangular vortex rings is achieved and then the unsteady forces can be evaluated.

Key words

hydrofoils unsteady flow vortex sheets water waves potential flow
