Current Energy Harnessing using Synergistic Kinematics of Schools of Fish-Shaped Bodies: Marine Hydrodynamics Laboratory Tank Testing Data

Published by Vortex Hydro Energy | Department of Energy | Metadata Last Checked: January 27, 2026 | Last Modified: 2022-01-17T07:00:01Z
The objectives of the proposed work pertain to building a high power-density and high efficiency device to harness MHK energy by mimicking fish-school kinematics. Vortex Hydro Energy is collaborating with a concept formed and undergone preliminary testing at the University of Michigan to complete this task. This submission contains data from the Marine Hydrodynamics Laboratory tank testing for 1, 2, and 3 cylinders. Tests were run in a 10,000 gallon recirculating tank. Cylinders have a diameter of 0.0889 m and 0.895m long. See "Read Me" for file format explanation and additional details.
