In this study, a two-dimensional oscillating foil with forward speed in a propagating wave flow field was considered.The time-mean power to maintain the heaving and pitching motions of the foil was analyzed using the perturbation theory in an ideal fluid.The power, which was a non-linear quantity Exercise Equipment - Upper Body of the second-order, was expressed in terms of the quadratic transfer functions related to the mutual product of the heaving and pitching motions and incoming vertical flow.The effects of the pivot point and phase difference among the disturbances were studied.The negative power, which indicates energy extraction from the Faber Daisy B EG6 A55 55cm Angled Cooker Hood Black Glass 330.0529.064 fluid, is shown as an example calculation.
