Dynamic stall at high Reynolds numbers induced by ramp-type pitching motions

J Kiefer, CE Brunner, MOL Hansen… - Journal of Fluid …, 2022 - cambridge.org
The transient pressure field around a moderately thick airfoil is studied as it undergoes ramp-
type pitching motions at high Reynolds numbers and low Mach numbers. A unique set of …

Investigation of Submergence Depth and Wave-Induced Effects on the Performance of a Fully Passive Energy Harvesting Flap** Foil Operating Beneath the Free …

N Petikidis, G Papadakis - Journal of Marine Science and Engineering, 2023 - mdpi.com
This paper investigates the performance of a fully passive flap** foil device for energy
harvesting in a free surface flow. The study uses numerical simulations to examine the …

Comparison of dynamic stall on an airfoil undergoing sinusoidal and VAWT-shaped pitch motions

CE Brunner, J Kiefer, M Hultmark - Journal of Physics …, 2022 - iopscience.iop.org
The aerodynamics of vertical axis wind turbines (VAWTs) are inherently unsteady because
the blades experience large angle of attack variations throughout a full turbine revolution. At …

Computational Fluid‐Structure Interaction towards Simulating Large Wind Turbines with openFOAM and deal. II Coupled via preCICE

K Mang, JD Ahrens, JR Seume, R Rolfes - PAMM, 2023 - Wiley Online Library
Wind energy is an essential part of the Green Deal. The trend to increase the size of wind
