, pitching amplitude θ0). The results reveal that the power extracted from the oncoming flow mainly comes from the plunging … motion and the pitching contribution is quite limited. Detailed examination of motion parameters indicates that at a fixed θ0 …-extraction efficiency for the oscillating foil in the frequency and pitching amplitude domain is presented. It is found that high k together …
