The three-dimensional flow generated by a flapping foil of finite 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 flow visualisations of Ref. 13. The vortex structures shed by the foil are analysed using different approaches. Even for a foil span equal to three foil chord the results are significantly different from the two-dimensional case.

Abstract
The three-dimensional flow generated by a flapping foil of finite 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 flow visualisations of Ref. 13. The vortex structures shed by the foil are analysed using different approaches. Even for a foil span equal to three foil chord the results are significantly different from the two-dimensional case.
