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…
Revealing the mechanism and scaling laws behind equilibrium altitudes of near-ground pitching hydrofoils
Tianjun Han, Qiang Zhong, Amin Mivehchi +2
A classic lift decomposition (von Kármán & Sears 1938) is conducted on potential flow simulations of a near-ground pitching hydrofoil. It is discovered that previously observed sta…
Two-dimensionally stable self-organization arises in simple schooling swimmers through hydrodynamic interactions
Pedro Costa Ormonde, Melike Kurt, Amin Mivehchi +1
We present new constrained and free-swimming experiments and simulations of a pair of pitching hydrofoils interacting in a minimal school. The hydrofoils have an out-of-phase synch…
Scaling Laws for the Propulsive Performance of a Purely Pitching Foil in Ground Effect
Amin Mivehchi, Qiang Zhang, Melike Kurt +2
Scaling laws for the thrust production and power consumption of a purely pitching hydrofoil in ground effect are presented. For the first time, ground effect scaling laws based on…
Intermittent Unsteady Propulsion with a Combined Heaving and Pitching Foil
Emre Akoz, Amin Mivehchi, Keith W. Moored
Inviscid computations are presented of a self-propelled virtual body connected to a combined heaving and pitching foil that uses continuous and intermittent motions. It is determin…
Scaling Laws for Three-Dimensional Combined Heaving and Pitching Propulsors
Fatma Ayancik, Amin Mivehchi, Keith W. Moored
We present new scaling laws for the thrust production and power consumption of three-dimensional combined heaving and pitching hydrofoils by extending the three-dimensional pitchin…
