The three-dimensional ow generated by a apping foil of nite span is numerically simulated by integrating continuity and momentum equations. The foil moves with a constant forward speed and oscillates both angularly and vertically. The numerical results are compared with ow visualisations of Ref. 13. The vortex structures shed by the foil are analysed using dierent approaches. Even for a foil span equal to three foil chord the results are signicantly dierent from the two-dimensional case.

Abstract
The three-dimensional ow generated by a apping foil of nite span is numerically simulated by integrating continuity and momentum equations. The foil moves with a constant forward speed and oscillates both angularly and vertically. The numerical results are compared with ow visualisations of Ref. 13. The vortex structures shed by the foil are analysed using dierent approaches. Even for a foil span equal to three foil chord the results are signicantly dierent from the two-dimensional case.File in questo prodotto:
