a b s t r a c tThe performance of a new type of flow energy harvester based on oscillating foils is investigated through numerical modeling by using two methods, a 2D thin-plate model and a 3D nonlinear boundary-element model. The fluid-structure interaction problem involved in the dynamics of a heaving/pitching foil coupled with an actuation/energy harvesting system in this device is examined. The 2D analysis allows us to simulate dynamics of the flapping-foil system over a large range of parameters and to identify areas of special interests (e.g., high energy output or high efficiency). In the vicinity of these areas the 3D model can accurately predict the performance of the system. By examining the power extraction capacity and efficiency of the system at various geometric, mechanical, and kinematic parameters, the optimal performance of the system is determined. In addition, the performance is found to be enhanced by the presence of a solid ground, as well as the thickness of the foil (at certain frequencies).

“…Oscillating wings can be used to extract energy from fluid flows, for example [30,14,16,48]. In this test case, we simulate flow over two tandem oscillating wings and study the energy extraction performance of this system.…”

“…By mimicking these heaving and pitching motions for generating thrust, engineers have designed micro air vehicles that are of interest for military and civilian applications [40]. On the other hand, heaving and pitching motions of air/hydro foils can also be utilized for energy harvesting [30]. A common feature of the flow fields around these objects is the existence of highly vortical flow structures, which are critical to the performance of the objects [3,36,44,7].…”

“…The concept of energy extraction from wind using flapping foils was initially proposed by McKinney and DeLaurier [3], and only in recent years has the energy harvesting mechanism draw much attention. The test work in a wind tunnel by McKinney and DeLaurier [3] showed that the energy extraction efficiency was comparable to that of wind turbines.…”
