Data-driven modeling of nonlinear events for an oscillating surge WEC using Sparse Identification of Nonlinear Dynamics (SINDy)

Brittany Lydon, Steven L. Brunton, Ama R. Hartman, Greg Talpey et autres

Accurate and computationally efficient models for wave energy converters (WECs) are critical for design and control development. Often, these models are based in linear potential flow theory, which has low computational cost, but may require restrictive assumptions that cannot account for complicated …

Performance data for an axial-flow turbine with passive adaptive blades

Katherine Van Ness, Corey Crisp, Brian L. Polagye

To support the development of simulation tools for passive adaptive turbine rotors, an experimental data set from a laboratory-scale axial-flow turbine with passive adaptive blades is provided. The 0.45-meter diameter turbine was tested in the Alice C. Tyler Flume at the University …

DAISY Benchmark Performance Data

Brian L. Polagye, Corey Crisp, Lindsey Jones, Paul M. Murphy et autres

This repository contains the underlying data from benchmark experiments for Drifting Acoustic Instrumentation SYstems (DAISYs) in waves and currents described in "Performance of a Drifting Acoustic Instrumentation SYstem (DAISY) for Characterizing Radiated Noise from Marine Energy Converters" (https://link.springer.com/article/10.1007/s40722-024-00358-6). DAISYs consist of a …

Wave energy converter power take-off characterization: comparing dynamometer and field data

Curtis J. Rusch, Corey Crisp, Erik Joel Hammagren, Joe Prudell et autres

Through dynamometer testing of a wave energy converter’s (WEC’s) power take-off system (PTO), we characterize friction and establish a relationship between shaft speed and torque. This characterization is conducted through oscillation of the shaft with a velocity-controlled motor, yielding some key differences …

Adaptable Distributed Sensing in Coastal Waters: Design and Performance of the μFloat System

Trevor W. Harrison, Corey Crisp, Jessica Noe, James Joslin et autres

Buoyancy-controlled underwater floats have produced a wealth of in situ observational data from the open ocean. When deployed in large numbers, or “distributed arrays,” floats offer a unique capacity to concurrently map 3D fields of critical environmental variables, such as currents, temperatures, …
