Rather than drafting, vortex capture dictates efficiency in three-hydrofoil schools
Pedro C. Ormonde, Yuanhang Zhu, Daniel Quinn +1
Three-dimensional experiments are presented on a school of three pitching hydrofoils. Two side-by-side leader foils maintain the same relative positions while the location of a thi…
Tuna-Like Swimmers Experience a Fluid-Mediated Stable Side-by-Side Formation
Pedro C. Ormonde, Matthew Stasolla, Alec Menzer +4
New free-swimming experiments and simulations are conducted on a pair of three-dimensional, bio-robotic swimmers composed of a body and tail section based on Yellowfin tuna, Thunnu…
Wavenumber affects the lift of ray-inspired fins near a substrate
Yuanhang Zhu, Leo Liu, Tianjun Han +4
Rays and skates tend to have different fin kinematics depending on their proximity to a ground plane such as the seafloor. Near the ground, rays tend to be more undulatory (high wa…
Tailoring formations of self-organizing hydrofoil schools towards high-efficiency
Tianjun Han, Amin Mivehchi, Seyedali Seyedmirzaei Sarraf +1
We present new unconstrained simulations and constrained experiments of a pair of pitching hydrofoils in a leader-follower in-line arrangement. Free-swimming simulations of foils w…
