Generation of an isolated vortex gust through a heaving and pitching foil
Bingfei Yan, Eric Handy-Cardenas, Kenny Breuer +1
This study introduces a vortex gust generation method for isolated vortices impacting a downstream airfoil that is applicable to both numerical simulations and experiments. The vor…
Vortices, turbulence, and center of pressure in flow over pitching swept wings
Dipan Deb, Yuanhang Zhu, Philip Gaudio +1
This study examines the center of pressure (CoP) movement of rigid pitching swept wings based on prior measurements by (Zhu, Breuer, 2023}. The wings analyzed feature sweep angles…
A data-driven approach for modeling large-amplitude flow-induced oscillations of elastically mounted pitching wings
Yuanhang Zhu, Kenneth Breuer
We propose and validate a data-driven approach for modeling large-amplitude flow-induced oscillations of elastically mounted pitching wings. We first train a neural networks regres…
Optimal Kinematics for Energy Harvesting Using Favorable Wake-Foil Interactions in Tandem Oscillating Hydrofoils
Eric E. Handy-Cardenas, Yuanhang Zhu, Kenneth S. Breuer
The energy harvesting performance of a pair of oscillating hydrofoil turbines in tandem configuration is experimentally studied to determine the optimal kinematics of the array. By…
Shape-morphing membranes augment the performance of oscillating foil energy harvesting turbines
Ilan M. L. Upfal, Yuanhang Zhu, Eric Handy-Cardenas +1
Oscillating foil turbines (OFTs) can be used to produce power from rivers and tides by synchronizing their heaving motion with the strong lift force of vortices shed at their leadi…
