Large-amplitude oscillations of foils for efficient propulsion

26 Sep 2019 Floryan Daniel Van Buren Tyler Smits Alexander J.

Large-amplitude oscillations of foils have been observed to yield greater propulsive efficiency than small-amplitude oscillations. Using scaling relations and experiments on foils with peak-to-peak trailing edge amplitudes of up to two chord lengths, we explain why this is so... (read more)
