Flapping-foil thrusters are systems that operate at a substantially lower frequency compared with marine propellers and are characterized by a much smaller power concentration. These biomimetic devices are able to operate very efficiently, offering d

In this paper, the accuracy of an in-house Actuator Line (AL) model is tested on aeroelastic simulations of a Wind Turbine (WT) rotor and a helicopter Main Rotor (MR) under uniform free-stream flow. For the scope of aeroelastic analyses, the AL model

Wind flow over forested areas is simulated using a 3-D Reynolds Averaged Navier–Stokes solver, employing the Wilcox k–ω model modified for atmospheric flows. Each tree is simulated individually with a two-region approach considering the leaf are
