Experimental evaluation of advanced control strategies for high-blockage cross-flow turbine arrays
Aidan Hunt, Gregory Talpey, Brian Polagye
In river or tidal channels, cross-flow turbines can achieve higher blockage ratios than other turbine variants, and are therefore able to achieve higher efficiencies. Here, we expe…
Near Wake Dynamics of a Cross-Flow Turbine Array
Isabel Scherl, Abigale Snortland, Steven Brunton +1
Cross-flow turbines, also known as vertical-axis turbines, convert the kinetic energy in moving fluid to mechanical energy using blades that rotate about an axis perpendicular to t…
Experimental identification of blade-level forces, torque, and pitching moment for cross-flow turbines
Abigale Snortland, Katherine Van Ness, Jennifer A. Franck +3
Cross-flow turbine power is a net sum of power generation from rotating blades and power loss from rotating support structures. While the aggregate forces and torques at the turbin…
Performance characteristics and bluff-body modeling of high-blockage cross-flow turbine arrays with varying rotor geometry
Aidan Hunt, Gregory Talpey, Gemma Calandra +1
While confinement is understood to increase the power and thrust coefficients of cross-flow turbines, how the optimal rotor geometry changes with the blockage ratio -- defined as t…
Experimental validation of a linear momentum and bluff-body model for high-blockage cross-flow turbine arrays
Aidan Hunt, Ari Athair, Owen Williams +1
In a confined flow, the performance of a turbine and its near-wake fluid dynamics depend on the blockage ratio, defined as the ratio of the turbine projected area to the channel cr…
Experimental techniques for evaluating the performance of high-blockage cross-flow turbine arrays
Aidan Hunt, Brian Polagye
In confined flows, such as river or tidal channels, arrays of turbines can convert both the kinetic and potential energy of the flow into renewable power. The power conversion and…
An experimental evaluation of the interplay between geometry and scale on cross-flow turbine performance
Aidan Hunt, Benjamin Strom, Gregory Talpey +5
Cross-flow turbines harness kinetic energy in wind or moving water. Due to their unsteady fluid dynamics, it can be difficult to predict the interplay between aspects of rotor geom…
Data-driven modeling of an oscillating surge wave energy converter using dynamic mode decomposition
Brittany Lydon, Brian Polagye, Steven Brunton
Modeling wave energy converters (WECs) to accurately predict their hydrodynamic behavior has been a challenge for the wave energy field. Often, this results in either low-fidelity,…
Cycle-to-cycle variations in cross-flow turbine performance and flow fields
Abigale Snortland, Isabel Scherl, Brian Polagye +1
Cross-flow turbine performance and flow fields exhibit cycle-to-cycle variations, though this is often implicitly neglected through time- and phase-averaging. This variability coul…
Effect of aspect ratio on cross-flow turbine performance
Aidan Hunt, Carl Stringer, Brian Polagye
Cross-flow turbines convert kinetic power in wind or water currents to mechanical power. Unlike axial-flow turbines, the influence of geometric parameters on turbine performance is…
