WebOct 26, 2016 · Energy harvesting using flapping foils has attracted significant attention in the last 10 years. In contrast to conventional turbines, which rely on attached flow for high efficiency, a flapping-foil turbine exploits the separation of fluid flow near the nose of the foil to form a leading-edge vortex, resulting in high instantaneous forces. To reduce the … WebMar 19, 2016 · Effect of constrained flow is investigated experimentally for a flapping foil power-generator. The flow structures around and in the near wake of a flat plate placed between two side walls...
